This research sought to understand the reasons for this \"hiatus\" in global warming and in particular the roles of the ocean and atmosphere in contributing to this hiatus through movement of energy around the climate system. This project has helped us monitor changes in climate and understand the processes that are important in enabling us to predict climate change more accurately over the coming decades. \r\n\r\nWarming of the planet is caused by a small yet persistent imbalance between the amount of sunlight absorbed by the Earth and the outgoing flow of thermal (infra-red) radiative energy constantly emanating from our planet to space: if more energy is arriving than leaving then the climate heats up. To understand why the heating has apparently slowed required a detailed assessment of the flows of energy arriving from space, how this energy is transported by the atmosphere, taken up by the surface ocean and subducted deep below the sea surface. Previously, scientists had identified a discrepancy between these energy flows, or \"missing energy\" in the climate. A primary objective of this research program was to resolve the discrepancy between these energy flows and understand the root causes of the hiatus in the warming of the Earth's surface. \r\n\r\nThe project combined the latest, improved satellite measurements of Earth's radiative energy imbalance (reflected sunlight and emitted thermal radiation) with the best estimates of energy flows in the atmosphere (from reanalysis simulations) and detailed 3-dimensional ocean heating measurements made by thousands of automated floating buoys, to determine the observed flows of energy in the climate system. The project combined these measurements with state-of-the-art depictions of Earth's climate from sophisticated computer simulations to understand the mechanisms by which the build up of energy due to greenhouse gas increases are redistributed into the oceans. \r\n\r\nIt is plausible that increased amounts of reflective aerosols in the atmosphere (due to human activities or naturally through emissions by volcanic eruptions) may have diminished the heating of the planet. However, preliminary analyses lead to the hypothesis that in fact more heat has been entering the deep ocean rather than heating the planets surface. Getting to the bottom of this question was vital for understanding current climate variability and future change over the coming 10 years or more. The project considered that the research is also important for understanding regional sea level rise (since warmer water occupies a larger volume leading to rising sea level), fluctuations in clouds and whether they magnify or reduce warming tendencies (climate feedbacks) and simulating the ocean circulation and heat uptake, crucial for representing climate change over the coming decades. \r\n\r\nThis research was only possible by combining the expertise from three institutions (the University of Reading, the National Oceanography Centre Southampton and the Met Office) covering satellite data, reanalyses of the atmosphere and ocean, ocean measurements and numerical computer simulations of the climate system. The current planetary changes are unusual and present a timely opportunity for understanding how our climate system works: to discover the cause of the global warming hiatus and to understand and simulate the mechanisms important in representing climate variability and change over the coming decades.\r\n\r\nThe primary objective of the project was to quantify Earth's Energy Imbalance, its variability and implications for climate change over the coming decades. The driving goal was to observe, understand and explain the slow rates of surface warming since 2000 using satellite data, atmospheric reanalyses, in situ observations of ocean heat content and climate simulations and to elucidate physical mechanisms operating during \"hiatus\" decades of slow surface warming rates through the following specific objectives: \r\n\r\n1) Combine CERES satellite radiation budget measurements with ERA Interim reanalysis and additional datasets, providing improved 2D estimates of surface heat fluxes entering the ocean surface since 2000 \r\n2) Develop and compute global 3D ocean heat and freshwater content and its changes since 2003 using ARGO observations, leading to improved understanding of energy propagation through the climate system \r\n3) Conduct multi-model assessment of simulated variability in ocean heat content, freshwater content and steric sea-level and evaluate the processes fundamental for ocean heat uptake and redistribution \r\n4) Provide accurate estimate of Earth's net radiative energy balance and its variability over the period 2000-2015 by combining results from (1-3) and compare with state-of-the-art CMIP5 climate simulations. \r\n5) Quantify and understand lags between OHC and top of atmosphere radiation involving additional minor energy storage terms in the climate system \r\n6) Characterise spatial signatures and mechanisms of ocean and atmospheric heat re-distribution during the period 2000-2015 using observations and multi-model simulations of variability in ocean heat content, freshwater content and steric sea-level \r\n\r\nMeeting these objectives also resulted in: \r\n\r\n7) Explain the previously documented discrepancy between energy flows (or\"missing energy\") in the climate system \r\n8) Generate legacy software and methodologies for monitoring changes in Earth's radiative imbalance \r\n\r\nAdditional outputs that stemmed from the project were: \r\n\r\n9) Computations of ocean-basin scale estimates of energy budget, \r\n10) Identification of key regions of energy subduction into the ocean on interannual-decadal time-scales \r\n11) Explore the potential for using deep hydrographic sections for quantifying changes deeper than 2000m and evaluate their significance. \r\n12) New knowledge for regional sea level, climate feedback and reanalysis/climate modelling communities (see Academic Beneficiaries)", "keywords": "", "status": "ongoing", "publicationState": "working", "identifier_set": [], "observationCollection": [], "parentProject": null, "subProject": [], "responsiblepartyinfo_set": [ "https://api.catalogue.ceda.ac.uk/api/v2/rpis/46219/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/46215/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/46220/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/46216/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/46214/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/46218/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/46217/?format=api" ] }, { "ob_id": 12147, "uuid": "6e6016d76b204d758388eab5470fbd98", "title": "Historical Ocean Surface Temperatures: Adjustment, Characterisation and Evaluation (HOSTACE)", "abstract": "The HOSTACE project was funded by the Natural Environment Research Council (NERC) with the grant reference - NE/J02306X/2 - led by Professor Christopher Merchant (University of Reading). \r\n\r\nThe surface temperature of the land and sea is the main measure of \"global warming\". Measurements of sea surface temperature (SST) have been made for more than 200 years, first on sailing ships, now on a mixture of ships and buoys (drifting and moored). Technology has changed dramatically over this period, raising serious questions about whether technology changes over time give a misleading impression of how the temperature has changed - and therefore how climate has changed. \r\n\r\nPeople first measured the temperature of a seawater sample hauled up in a wooden bucket. Buckets are now made of insulating rubber. Most direct SST measurements are now sent via satellites from drifting buoys. Many other measurement methods have also been used. Different methods don't yield precisely the same SST values, and because global warming is a gradual change, these subtle discrepancies (or \"biases\") could distort our picture about the timing and magnitude of global warming. So, we must be sure that we understand how the different methods used to measure SST have affected the observations.\r\n\r\nThese biases in SST have been a known problem for years, so why do we believe we can solve it? One reason is that recently many more observations have been retrieved from historical sources. Many ships' logbooks containing weather observations have been digitised. This has nearly doubled the number of observations before World War 2. Another reason is new, stable observations of SST from sensors on satellites orbiting Earth. Most satellite sensors give a detailed picture of patterns in SST and are tuned to drifting buoy SSTs to give reasonable accuracy. But compared to the subtle trends of global warming, they are not stable enough from year to year and across large distances. New high-quality SST measurements from a reworking of the SST measurements of a particular series of sensors are accurate and stable enough. Even better, they do not rely on ship or buoy SST observations, so we can use them as an independent point of reference. \r\n\r\nA major challenge is that the biases in SST made on ships are different for different measurement methods and we don't always know what methods were used. But we do know how we expect the biases for each method to vary with factors like the amount of heating by the Sun and wind speed. The project used these variations of the biases for each ship or buoy to assign measurement methods to observations (or, where it is not clear cut, the likelihood that the method is one or another type). E.g., we might be 80% confident that a particular ship used a canvas bucket to sample the water, but allow a 20% chance that a wooden bucket was used. The project then adjusted for the expected biases according to method, and indicated how uncertain the adjustment may be. \r\n\r\nThe next step was to combine the scattered observations into maps of monthly average SST over the whole ocean. They also calculated the degree of uncertainty in these monthly maps. There were few observations in the 19thC, so a global SST map required sophisticated gap-filling methods. The final step was to compare the projects maps of SST with those produced by other scientists. Normally when such comparisons are made it is hard to understand the source of differences between the datasets. Was it due to different input data? Or different bias adjustments? Or the way the gaps were filled? Collaborating with other dataset producers, the project separated these different effects. For example, they all used identical inputs, and isolated the effects of different gap-filling methods. This also tested the uncertainty estimates - if important factors affecting the SST biases have been missed, then estimates of uncertainty may be too small to explain the differences between the SST maps produced by different groups.\r\n\r\nSuch problems can mislead us in interpreting climate changes. The project used the new SST history to reassess explanations of phases of climate warming during the 20thC.\r\n\r\nHistorical sea surface temperature (SST) is a crucial parameter for climate change science but the high degree of present uncertainty in our knowledge of it is underestimated. This projects aims were to radically revise understanding of historical SST by quantifying the bias and uncertainty of SST observations throughout the instrumental record and to produce a new bias-adjusted gridded SST analysis quantified with credible estimates of uncertainty. In this way, use of recently recovered historical data and new climate-quality satellite data allowed us to improve our understanding of the evolution of centennial climate change. As an example, the project used the new historical SSTs to attribute the causes of the early 20thC warming. This is one of many areas where the results will advance understanding of climate, leading to increased confidence in predictions of future change.\r\n\r\nSpecific objectives of this project were:\r\n\r\nO1: Quantification, correction and validation of in situ SST bias for the entire observational record (from 1850 or earlier, to present)\r\nO2: Assessment of measurement, sampling and residual bias uncertainty in the in situ SST record\r\nO3: Development and publication of a new long-term bias-adjusted SST gridded analysis with estimates of measurement, sampling and residual bias uncertainty along with their correlations\r\nO4: Quantification of methodological uncertainty in gridded analyses of SST through an international SST dataset comparison exercise\r\nO5: Application of new SST to elucidate drivers of early 20thC climate change\r\n\r\nThe objectives directly addressed challenges in the Climate System theme of the NERC strategy:\r\n\r\n- Increase knowledge of natural climate variability, and diagnose and improve its representation in climate models\r\n- Provide accurate observations of the global climate system for long-term monitoring of climate to quantify changes and to test and evaluate climate models\r\n\r\nThe project argued that available uncertainty estimates in SST analyses are too small, leading to over-confidence in the estimates of trends and variability, and problems in understanding 20thC climate variability with climate models. Objectives 1 and 2 address problems with accurately estimating the uncertainty. Objective 3 applied the knowledge gained from 1 and 2 to develop a new SST analysis, including uncertainty estimates, for use in: assessment of climate change and our confidence in those changes; understanding the variability of the SST on long time-scales and validation of climate models. Objective 4 sought to address the uncertainty in our assessments and SST analyses due to methodological choices (\"structural uncertainty\"). Objective 5 applied the new SST analysis in a study to attribute the cause of early 20thC climatic change.", "keywords": "", "status": "ongoing", "publicationState": "working", "identifier_set": [], "observationCollection": [], "parentProject": null, "subProject": [], "responsiblepartyinfo_set": [ "https://api.catalogue.ceda.ac.uk/api/v2/rpis/46221/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/46222/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/46225/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/46223/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/46226/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/46224/?format=api" ] }, { "ob_id": 12148, "uuid": "407621ad08204f96a68708ceaf8cac2e", "title": "High accuracy line intensities for carbon dioxide", "abstract": "This project was funded by the Natural Environment Research Council (NERC) with the grant reference - NE/J010316/1 - led by Professor Jonathan Tennyson (University College London). \r\n\r\nAll CO2 remote sensing activity, from both the ground and space, relies on monitoring how CO2 absorbs light. All this monitoring is therefore heavily dependent on understanding the absorption properties of the CO2 molecule which is usually obtained by measurements performed in the laboratory. In particular the accurate knowledge of the strength of individual absorption lines is crucial to determining how much CO2 is present and allowing the atmospheric data to be interpreted. Without high accuracy values for line intensities, reliable CO2 retrievals are simply not possible. Particularly with their emphasis on variation of CO2 concentrations with time, current missions and proposed missions require CO2 line intensities to be determined to significantly better than 1% accuracy if they are to fulfill their stated goals: intensities accurate to better than 0.5% are really required. Current line intensities measured in the laboratory simply do not gives this level of accuracy: most are accurate to about 5% with a few high quality measurements being good to 1 - 3%. Hence current CO2 retrievals values are limited by the available laboratory data. \r\n\r\nThe aim of this project was to provide an accurate theoretical solution to the problem of CO2 line intensities based on the application of high accuracy, first principles quantum mechanical calculations for the intensities and experimental data for the line positions.

These reconstructions are founded on an understanding of theoretical and statistically-derived associations acquired by comparing the parallel behaviour of palaeoclimate proxies and measurements of varying climate. Inferences about variations in past climate, based on this understanding, necessarily assume that the associations we observe now hold true throughout the period for which reconstructions are made. This is the essence of the uniformitarian principle. \r\n\r\nIn some northern areas of the world, recent observations of tree growth and measured temperature trends appear to have diverged in recent decades, the so called 'divergence' phenomenon. There has been much speculation, and numerous theories proposed, to explain why the previous temperature sensitivity of tree growth in these areas is apparently breaking down. The existence of divergence casts doubt on the uniformitarian assumption that underpins a number of important tree-ring based (dendroclimatic) reconstructions. It suggests that the degree of warmth in certain periods in the past, particularly in medieval times, may be underestimated or at least subject to greater uncertainty than is currently accepted. \r\n\r\nThe lack of a clear overview of this phenomenon and the lack of a generally accepted cause had led some to challenge the current scientific consensus, represented in the 2007 report of the IPCC on the likely unprecedented nature of late 20th century average hemispheric warmth when viewed in the context of proxy evidence (mostly from trees) for the last 1300 years. \r\n\r\nThis project will seek to systematically reassess and quantify the evidence for divergence in many tree-ring data sets around the Northern Hemisphere. It will establish a much clearer understanding of the nature of the divergence phenomenon, characterising the spatial patterns and temporal evolution. \r\n\r\nBased on recent published and unpublished work by the proposers, it has become apparent that foremost amongst the possible explanations is the need to account for systematic bias potentially inherent in the methods used to build many tree-ring chronologies including many that are believed to exhibit this phenomenon. This proposal is designed to build on recent innovations in tree-ring chronology production techniques, also developed by the proposers. These new methods will produce tree-ring chronologies whose variability is unbiased, either by temporal changes in the age structure of the constituent sample series, or by any distortion in the data that can arise when using the previously applied techniques. The extensive reprocessed and improved data sets will then form the basis for many detailed, site-by-site comparisons of local climate and various tree-growth parameters in order to re-characterise the nature, strength and temporal stability of the climate/growth associations. This will represent a systematic and objective re-assessment of the evidence for divergence in different forest contexts.\r\n\r\nThe project will then explore all of the current theories for the cause(s) of divergence employing both statistical and process-modelling techniques. The project will go on to use the reprocessed tree-ring data sets to re-calibrate many important climate reconstructions, with varying levels of spatial detail, and carefully assess the implications of the divergence effect, as newly characterised, on reconstruction uncertainty. This project will provide results that will inform the international scientific debate and widespread public perception of the reliability of tree-ring-based climate reconstructions in particular, but also our current understanding of the reliability of current evidence for high-resolution temperature changes during the late Holocene. \r\n\r\nThis project was funded by the Natural Environment Research Council (NERC) for three and a half years from May 2010 to October 2013 (NERC Reference: NE/G018863/1).\r\n\r\nData can be found on the website below.

One of the first events that increased the public's awareness of environmental issues was the discovery of the Antarctic ozone hole in the 1980s. Ozone is a gas that comprises only a tiny fraction of all the gases that make up the atmosphere but it is very important in climate. At high altitudes (about 15 to 30 km), there is lots of ozone which is good thing for the planet, as it shields the Sun's harmful UV radiation. However, ozone is a toxic substance and if it builds up within the troposphere (the lowermost part of the atmosphere) and at the surface then this is not good. Tropospheric ozone is bad for us because it is (a) a greenhouse gas, and (b) and air pollutant that affects the human respiratory system and agricultural crop yields. Ozone is produced near the surface when substances known as volatile organic compounds (VOCs) are emitted from the surface and subsequently react within the atmosphere. VOCs can be emitted from human activities, but they are predominantly emitted by vegetation that grows on land. Of all the biogenic VOCs emitted into the atmosphere, none is more important than isoprene owing to its ability to quickly react with other compounds (to produce tropospheric ozone) and because it is emitted in large amounts. Isoprene is also important, as it is a source of very small particles called secondary organic aerosol (SOA) that scatter light, which influences how the Earth warms, and which also have adverse health effects. We need to know (a) when, (b) where and (c) how much isoprene is emitted into the atmosphere in order to better understand tropospheric ozone and SOA. Currently we use generic computer models that are based on observations to simulate the amount of isoprene emitted from different types of vegetation, such as trees or grasses. Isoprene emissions from the Amazon Basin, which contains the world's largest rain forest and is thought to be one of the biggest isoprene sources, are poorly quantified since it is very difficult to measure the emissions in this largely inaccessible and remote region. Satellite observations of a gas called formaldehyde (HCHO), contain information on isoprene emissions, and can be used to determine the amount of isoprene emitted from terrestrial vegetation. The overall goal of my proposal is to use satellite observations of HCHO to accurately quantify isoprene emissions from the Amazon Basin. To achieve this goal I will develop a new unique high resolution model for the Amazon, which will be able to simulate isoprene emissions and atmospheric chemistry at finer spatial scales than have been able previously. I will then compare the isoprene emissions from this 'bottom-up' model with the 'top-down' isoprene emissions inferred from the satellite observations of HCHO, to identify regions or time periods where there is significant disagreement between the model and the observations, which highlights where we have poor understanding of the isoprene emissions. I will then develop an improved isoprene emission model by fine tuning the 'bottom-up' emission model to the inferred 'top-down' emissions, taking into account individual scenes (utilizing the high spatial resolution of the nested-grid) and different seasons. By reconciling the differences between the 'bottom-up' model and the 'top-down' emissions we will gain a more accurate estimate of how much isoprene is emitted from the Amazon, and more importantly gain a better understanding of the factors that influence when it is emitted. This research is important because the Amazon Basin is also one of the regions identified as being most susceptible to climate change, and it is crucial we determine the key factors that influence its isoprene emissions in order to improve confidence in our ability to predict future climate. \r\n\r\nObjectives: \r\n\r\n1) Develop a high resolution, nested-grid chemistry-transport model, centred over the Amazon, which will be driven using two bottom-up isoprene emission models that are based on fundamentally different approaches to simulate isoprene fluxes \r\n\r\n2) Compare the simulated isoprene emissions and oxidation products, from the two bottom-up inventories, against each other and in situ observations to assess which is more accurate \r\n\r\n3) Optimally estimate Amazon isoprene emissions using a Bayesian approach constrained by satellite observations of formaldehyde \r\n\r\n4) Develop emission model parameterizations that will reconcile the spatial and temporal differences between the top-down and bottom-up estimates \r\n\r\n5) Quantify the difference of the bottom-up and top-down isoprene emissions on the Amazonian atmospheric chemistry\r\n\r\nThis project was funded by NERC under grant NE/G013810/1.", "keywords": "nerc, research mode, amazon, isoprene", "status": "completed", "publicationState": "published", "identifier_set": [ "https://api.catalogue.ceda.ac.uk/api/v2/identifiers/8370/?format=api" ], "observationCollection": [ "https://api.catalogue.ceda.ac.uk/api/v2/observationcollections/3823/?format=api" ], "parentProject": "https://api.catalogue.ceda.ac.uk/api/v2/projects/1341/?format=api", "subProject": [], "responsiblepartyinfo_set": [ "https://api.catalogue.ceda.ac.uk/api/v2/rpis/53069/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/53068/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/53070/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/46902/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/46903/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/54752/?format=api" ] }, { "ob_id": 12273, "uuid": "5fcda0aef03b4f0eaa2a665c69b5e029", "title": "Snow-Vegetation-Atmosphere Interactions over Heterogeneous Landscapes Project", "abstract": "By modifying the amount of solar radiation absorbed at the land surface, bright snow and dark forests have strong influences on weather and climate; either a decrease in snow cover or an increase in forest cover, which shades underlying snow, increases the absorption of radiation and warms the overlying air. \r\n\r\nComputer models for weather forecasting and climate prediction thus have to take these effects into account by calculating the changing mass of snow on the ground and interactions of radiation with forest canopies. Such models generally have coarse resolutions ranging from kilometres to hundreds of kilometres. Forest cover cannot be expected to be continuous over such large distances; instead, northern landscapes are mosaics of evergreen and deciduous forests, clearings, bogs and lakes. Snow can be removed from open areas by wind, shaded by surrounding vegetation or sublimated from forest canopies without ever reaching the ground, and these processes which influence patterns of snow cover depend on the size of the openings, the structure of the vegetation and weather conditions. Snow itself influences patterns of vegetation cover by supplying water, insulating plants and soil from cold winter temperatures and storing nutrients.\r\n\r\nThe aim of this project was to develop better methods for representing interactions between snow, vegetation and the atmosphere in models that, for practical applications, cannot resolve important scales in the patterns of these interactions.\r\n\r\nInformation was gathered on distributions of snow, vegetation and radiation during two field experiments at sites in the arctic: one in Sweden and the other in Finland. These sites were chosen because they have long records of weather and snow conditions, easy access, good maps of vegetation cover from satellites and aircraft and landscapes ranging from sparse deciduous forests to dense coniferous forests that are typical of much larger areas. \r\n\r\nUsing 28 radiometers, and moving them several times during the course of each experiment, allowed us to measure the highly variable patterns of radiation at the snow surface in forests.\r\n\r\nInformation from the field experiments have been used in developing and testing a range of models. To reach the scales of interest, we began with a model that explicitly resolves individual trees and work up through models with progressively coarser resolutions, testing the models at each stage against each other and in comparison with observations.

Each ring within a tree represents one year of growth and contains within it a record of the prevailing environmental conditions. Trees can thus be age dated, and used as a record of climate change through ring-width analysis and chemical composition. \r\n\r\nHowever, chemical interpretations of the nutrient chemistry within each ring have often been subject to much criticism. The basic premise that nutrients which are taken up by the tree are encapsulated to represent environmental conditions for that particular year, is true only for elements which are immobilised from further biological transport accross the width of the tree.\r\n\r\nWe now think we have found such an element which is fixed within the woody tissues during growth and can be used with certainty for environmental reconstruction - this element is sulphur. \r\n\r\nThat sulphur should be the element which is fixed within the annual growth rings is fortuitous given its key role in modulating climate and fantastic potential as an environmental diagnostic tool. The injection of sulphur aerosol into the atmosphere is a key determinant of climate through backscattering and absorption of radiation, and has long been a concern for terrestrial ecology, causing widespread acidification of catchments upon deposition. \r\n\r\nTwo of the key sources of sulphur aerosol injected into the atmosphere are from volcanic and industrial emissions. Both sources can be readily distinguished from background inputs using concentrations and stable isotopes, rendering the sulphur isotopic content of palaeoarchives to be perhaps one of the most important diagnostic elemental signatures available.\r\n \r\nWhilst the sulphur isotopic content of ice cores has been extensively exploited, the more localised archives such as speleothems and tree rings have largely remained beyond the reach of climate change scientists and we have yet to discover many of the secrets they harbour. \r\n\r\nWhilst we have initiated and had excellent success with extracting the sulphur record from speleothems, we believe trees will behave as a much more sensitive, readily available record of local atmospheric change over the past millenium. We believe we are now in a position to conduct an intensive research programme to extract the sulphur isotopic composition of trees and forge ahead with the development of such an important local indicator of sulphur forcing and atmospheric change.\r\n\r\nThis project is funded by the Natural Environment Research Council (NERC) for one and a half year from September 2010 to May 2012 (NERC Reference: NE/H012257/1).\r\n", "keywords": "NERC, sulphur, tree", "status": "completed", "publicationState": "published", "identifier_set": [ "https://api.catalogue.ceda.ac.uk/api/v2/identifiers/8372/?format=api" ], "observationCollection": [ "https://api.catalogue.ceda.ac.uk/api/v2/observationcollections/13790/?format=api" ], "parentProject": "https://api.catalogue.ceda.ac.uk/api/v2/projects/1341/?format=api", "subProject": [], "responsiblepartyinfo_set": [ "https://api.catalogue.ceda.ac.uk/api/v2/rpis/52430/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/52428/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/52429/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/46908/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/46911/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/54753/?format=api" ] }, { "ob_id": 12275, "uuid": "2b90309824f548a9be5159082842e669", "title": "Stratospheric Network for the Assessment of Predictability (SNAP)", "abstract": "Forecasting the weather from days to two weeks in advance has typically focused on the troposphere, the layer of the atmosphere closest to the ground.

Ozone and particulate matter are pollutants that are particularly harmful to human health. Recent studies have suggested that in the UK alone they cause 50,000 extra deaths and result in a financial burden of 8-22 billion pounds per year. Both ozone and particulate matter also play an important role in climate change. Ozone absorbs infra-red radiation resulting in a warming of the climate. Particles scatter and absorb incoming solar radiation and alter the properties of clouds. This results in complex interactions with the Earth's climate, with some types of aerosol pollution warming climate whereas others cool climate. Future air quality depends both on changes to emissions of pollutants and to changes in climate. Furthermore, a warming climate can result in worsened air pollution, which in turn can drive additional warming, meaning that complex feedbacks are possible between air pollution and climate.\r\n\r\nTo help understand these complex interactions and feedbacks scientists have developed Earth System Models that include a description of the important physical and biogeochemical processes. These models are increasingly being used by policy makers to make predictions about future air quality and climate and to guide policy decisions. It is therefore important that the models are rigorously tested. \r\n\r\nThis testing involves using detailed observations of atmospheric composition that have been made over the past few decades at locations around the world. Most model evaluation to date has involved testing whether the models simulate current average concentrations of atmospheric pollutants. Whilst this is a useful and necessary first step in model evaluation it does not test whether the model accurately simulates the change in concentration of a pollutant under changing emissions or changing climate. For example, does the model capture the real-world change in concentrations of a pollutant given a particular change in emission or under a future climate change scenario? This is particularly important as these predictions under-pin policy recommendations for air quality abatement. \r\n\r\nThis project synthesised long-term (multi-decadal) observations of ozone and particulate matter and their atmospheric precursors. They used these observations to explore trends and variability that have been observed over the past few decades. A model-observation framework was developed that can be used to evaluate how well models simulate observed variability and trends. The project tested state-of-the-art Earth System Models using existing model output from model intercomparison exercises.

The grants were led by Dr William Bloss (University of Birmingham), Professor Claire Reeves (University of East Anglia) and Professor Dwayne Ellis Heard (University of Leeds) respectively. \r\n\r\nTropospheric ozone is an important air pollutant, harmful to human health, agricultural crops and vegetation. It is the main precursor to the atmospheric oxidants which initiate the degradation of most reactive gases emitted to the atmosphere, and is an important greenhouse gas in its own right. As a consequence of this central role in atmospheric chemistry and air pollution, the capacity to understand, predict and manage tropospheric ozone levels is a key goal for atmospheric science research. This goal is hard to achieve, as ozone is a secondary pollutant, formed in the atmosphere from the complex oxidation of VOCs in the presence of NOx and sunlight, and the timescale of ozone production is such that a combination of in situ chemical processes, deposition and transport govern ozone levels. Uncertainties in all of these factors affect the accuracy of numerical models used to predict current and future ozone levels, and so hinder development of optimal air quality policies to mitigate ozone exposure. The project addressed this problem by measuring the local chemical ozone production rate, and (for the first time) perform measurements of the response of the local atmospheric ozone production rate to NOx and VOC levels - directly determining the ozone production regime. \r\n\r\nThe project aimed to achieve this by building upon an existing instrument for the measurement of atmospheric ozone production rates (funded through a NERC Technology Proof-of-Concept grant, and deployed in the recent ClearfLo 'Clean Air for London' NERC Urban Atmospheric Science programme). In addition to directly measuring ozone production, by perturbing the ambient chemical conditions (for example, through addition of NOx or VOCs to the sampled airflow), and measuring the effect of this change upon the measured ozone production rate, the ozone control regime (extent of NOx vs VOC limitation) may be directly determined. Within the project, they developed an existing ozone production instrument to include this capability, and validated the measurements, through comparison with ozone production from VOC oxidation in a large simulation chamber, and by measurement of the key oxidant OH radicals, and their precursors, within the system. \r\n\r\nICOZA then applied the instrument to compare the measured ozone production rates with those calculated using other observational and model approaches, and to characterise the ozone control regime, in two contrasting environments: In the outflow of a European megacity (at Weybourne Atmospheric Observatory, WAO, in the UK), and in a rural continental location (at Hohenpeissenberg, HPB, in southern Germany). At WAO, the project compared the measured ozone production rate with that calculated through co-located measurements of HO2 and RO2 radicals (using a newly developed approach to distinguish between these closely related species), and with that simulated using a constrained photochemical box model. They then compared the NOx-dependence of the ozone production rate with that predicted using indicator approaches, based upon observations of other chemical species. At HPB, they focused upon the VOC-dependence of the ozone production rate, and assess the error in model predictions of ozone production, which arise from the presence of unmeasured VOCs.\r\n\r\nThe project developed and demonstrated a new measurement approach, and applied this to improve the understanding of a fundamental aspect of atmospheric chemical processing. Future applications have considerable potential both to support atmospheric science research, but also as an important air quality tool, alongside existing measurement and modelling approaches, to inform the most effective emission controls to reduce ozone production in a given location. In the context of global crop yield reductions arising from ozone exposure of 7 - 12 % (wheat), 6 - 16 % (soybean) and 3 - 4 % (rice), this is an important societal as well as scientific impact. \r\n\r\nThe aim of the ICOZA project was to develop, refine and apply in situ measurements of the local chemical ozone production rate and its response to NOx and VOC levels. They aimed to assess the accuracy of model predictions of ozone production rates, and the systematic errors which arises from the presence of unmeasured species and/or limitations in our understanding of the atmospheric chemistry, through field observations in two contrasting environments. \r\n\r\nThe specific objectives were :\r\n\r\n1. To establish and validate the Perturbed Ozone Production Rate (POPR) concept, through laboratory development and simulation chamber testing\r\n\r\n2.

These grants were led by Professor Christopher Merchant, Dr Mark Cutler, Mr Stephen Groom, Professor Stephen Maberly and Dr Claire Miller respectively. \r\n\r\nThere are around 304 million lakes globally. These provide essential resources for human survival and are an important component of global biogeochemical cycles. Lakes are also fragile systems that are sensitive to multiple pressures including nutrient enrichment, climate change and hydrological modification, making them important 'sentinels' of environmental perturbation. However, traditional monitoring has only produced data from a tiny fraction of the global population of lakes and disentangling the causes of change requires consistently-produced data from a large number of lakes, along with measurements of possible causes of change. Satellite observations (remote sensing) and the establishment of a global lake observatory would produce a step-change in our ability to detect and attribute the causes of changes in lakes world-wide. \r\n\r\nThis is now possible for three reasons: \r\n(1) the improved wavebands, spatial resolution and frequency of data collection from satellite sensors is now sufficient to monitor inland waters; \r\n(2) formulae to correct for atmospheric properties and to convert the detected reflected light to useful lake properties have been developed; and \r\n(3) computing power has increased to the point that allows near real time and archived information from satellites to be processed. \r\n\r\nGloboLakes analysed 20 years of data from more than 1000 large lakes across the globe to determine 'what controls the differential sensitivity of lakes to environmental perturbation'. \r\n\r\nThis was an ambitious project that was only possible by bringing together a consortium of scientists with complementary skills. These included expertise in remote sensing of freshwaters and processing large volumes of satellite images, collation and analysis of large-scale environmental data, environmental statistics and the assessment of data uncertainty, freshwater ecology and mechanisms of environmental change and the ability to produce lake models to forecast future lake conditions. \r\n\r\nThe eight objectives of GloboLakes were to:\r\n(i) develop remote sensing algorithms to estimate lake biogeochemical and physical parameters;\r\n(ii) make these algorithms operational and process satellite data;\r\n(iii) compile integrated spatio-temporal information on climatic and catchment data for >1000 lakes;\r\n(iv) integrate data and assess uncertainty in data sources;\r\n(v) detect spatial and temporal patterns in lake water quality;\r\n(vi) attribute the causes of lake response to environmental conditions;\r\n(vii) forecast lake sensitivity to environmental change;\r\n(viii) apply data to lake management and the monitoring of freshwater resources.\r\n\r\nThe project focused on the retrieval of surface water temperature as this has a fundamental effect on lake ecology, the concentration of coloured dissolved organic matter and suspended solids that derive largely from the catchment, the abundance of phytoplankton measured as the concentration of the pigment, chlorophyll a, and the abundance of cyanobacteria (blue-green algae) that can potentially be toxic. Knowledge of the conditions of lakes and their sensitivity to change is also extremely valuable for the management of lakes and reservoirs and GloboLakes provided information and products specifically for environmental managers. \r\n\r\nA satellite launched during the course of the project, called Sentinel 2, provided even greater spatial resolution allowing data to be collected and exploited from even smaller lakes.

These were led by Professor Alan Blyth (University of Leeds) and Professor Thomas William Choularton (The University of Manchester)\r\n\r\nThe goal of this research was to determine how desert dust affects the nucleation of ice particles in convective and layer clouds and the subsequent development of precipitation and glaciation of the clouds. Dust is believed to be a critical aerosol particle in the Earth system mainly because the dust particles themselves, and particles that are chemically and possibly biologically modified as they are transported from their source, are believed to be the most important ice nuclei in a global sense and because dust particles are transported to many parts of the globe. Predicting the initiation and subsequent evolution of the size distribution of ice particles in clouds from a distribution of aerosol particles is one of the most important problems in atmospheric science. It is fundamental to the NERC high-level strategy objective ``Understand and predict how our planet works'', because the lack of understanding of the processes causes uncertainty in the way global models treat the interaction of radiation with ice and mixed-phase clouds and the development of precipitation. They also cause uncertainty in Numerical Weather Prediction (NWP) models, which is concerned with the NERC strategy objective ``Resilience to environmental hazards''. The proposed research aims was to tackle this problem by making measurements of aerosols and cloud particles close to one of the largest sources of desert dust in the world. The measurements are difficult to make, which is why such detailed measurements have never been made in this region before. It is possible to do this now because the instruments are capable of determining the chemical and physical properties of aerosol particles, the aircraft cloud physics instruments can detect small ice particles, and there is a mobile dual-polarisation radar. \r\n\r\nThe UK Ice in Clouds Experiment -- Dust (UK ICE-D) was part of the US-UK aircraft and ground-based project based in Cape Verde off the coast of Senegal, Africa to be held in 2015 (mainly UK) and 2016 (mainly US). Measurements will be made in the environment around the clouds to characterise the aerosol particles and their ability to act as ice nuclei and cloud condensation nuclei, and within the clouds to determine the influence of the particles on the cloud properties. Convective clouds will be measured as a priority, but layer clouds will also be targeted. Observations will be made when dust is present in high concentrations at appropriate altitudes and when almost no dust is present. The availability of the US and UK aircraft has inadvertently provided a unique opportunity to maximise the sampling statistics of the clouds. The location and time was selected from climatology studies because dust concentrations are often large and convective and layer clouds also occur frequently. In addition, the convective clouds in the region are known to be important since they can form clusters that lead to storms and hurricanes in the Tropical Atlantic.\r\n\r\nSpecifically, UK ICE-D made measurements on days with and without the presence of dust of the following:\r\n* Aerosol particles on the ground with the instruments in the aerosol container at Cape Verde and with the BAe 146 aircraft;\r\n* Cloud droplets, supercooled raindrops, the first ice particles and development of ice and precipitation particles with the aircraft;\r\n* The altitudes of the supercooled raindrops, the location and time of the first precipitation echoes, and the radial air motions using the radar;\r\n* The thermodynamics and dynamics of the clouds and their environment with the aircraft and to some extent the radar.\r\n\r\nModel results were compared with the observations of the initiation temperatures and rates of growth and development. A spectrum of models ranging from climate through regional forecast models to explicit cloud physics process-based models, will be used as forecasting tools and as tools to interpret the data and to develop or\r\n\r\nObjectives: \r\n1. Characterise the chemical and physical properties of aerosol particles and determine the activation properties of CCN and IN.\r\n\r\n2. Given an initial well-characterised aerosol distribution, can we predict the number concentration of ice particles that will be produced in the clouds through primary nucleation? Specifically, determine if primary ice particles first form as a result of freezing of supercooled raindrops. \r\n\r\n3. Determine the physical processes responsible for the production of warm rain and the rates of growth. E.g. is the process dependent on entrainment and mixing or determined by straightforward autoconversion or by giant CCN.\r\n\r\n4. Determine whether the HM secondary ice formation process is critical to the glaciation of the convective clouds and if so (likely) the effect of dust on the process. \r\n\r\n5. Determine the influence of dust on the physical properties of the convective and layer clouds (e.g.\\ dynamics, entrainment, liquid water content distribution, development of precipitation) and if the effects can be represented with models of all scales.\r\n\r\n6. Use the new observations to test and improve the ability of regional NWP, global NWP and climate models to accurately simulate the properties of clouds and their environment.

The focus of this project was on testing various hypotheses about the possible causes of the Little Ice Age. A carefully-designed set of model experiments (incorporating novel methods of assimilating information on climate time scales) were proposed, with the outputs assessed through comparison against empirical palaeoclimate evidence for climate variations over the past millennium. Specifically exploreed whether the Little Ice Age climate could have been generated by one or more of the following factors: a weakening of the Atlantic thermohaline circulation; the persistence of a generally negative North Atlantic Oscillation; or reduced radiative forcing (by increased volcanic activity, reduced solar insolation and lower greenhouse gas concentrations relative to the present).

This project was funded by: NCAR/UCAR Atmospheric Chemistry and Modeling Visiting Scientist Program, NCAS, University of Leeds School of Earth and Environment. \r\n\r\nThe VolcanEESM project presents a volcanic sulphur dioxide (SO2) emissions database for use in Earth System models. The database provides a comprehensive list of volcanic eruptions that were reported to emitted significant amounts of SO2 from 1850 to present.

The challenge was to understand the causes of the observed small, long-term changes in ozone. In particular, chemically induced loss had to be separated from change due to transport. This was a much more difficult problem than in the Antarctic spring where ozone loss is very substantial, and where transport plays a relatively small role.\r\n\r\nOzone loss in the Arctic has been substantial in recent winters. However, the appearance of low ozone at a particular altitude does not necessarily imply that chemical destruction of ozone has occurred. Low ozone could instead have been transported, horizontally or vertically, from another location. To confirm the processes involved, coincident measurements of long-lived tracers are required.\r\n\r\nObjectives \r\nThe overall scientific objective within this proposal was to contribute to the understanding of middle latitude ozone loss by making measurements of a number of important tracers of atmospheric motion and photochemistry, and by interpreting these measurements with state-of-the-art models of atmospheric chemistry and transport. \r\n\r\nThe particular aim of the proposal was to extend THESEO measurements of tracer and chemically active gases both spatially and temporally to provide more comprehensive coverage in the middle latitude low stratosphere and upper troposphere. The measurements were complement the similar EU funded measurements whose focus were primarily high and mid-latitudes in 1998/99. They were part of THESEO 2000 which was an extension of THESEO and which formed the basis of European collaboration with US SOLVE experiment which is studying Arctic ozone loss in the 1999/2000 winter. \r\nTogether, these measurements provide a unique data set for the study of chemistry and transport processes at mid latitudes. They studied annual transport through the middle latitude lower stratosphere and the processes of mixing with tropical and polar air. \r\n\r\nData were interpreted using 3D chemical transport models already developed at Cambridge. The large amount of data collected in polar middle and tropical latitudes during THESEO provided a unique opportunity for the new mid-latitude data to contribute to the understanding of middle latitude ozone decline and, in particular, to understanding the relative importance of in situ ozone loss and transport from other regions.\r\n\r\nBalloon flights were made from Esrange Kiruna station during the 1999/2000 winter, with balloon payloads incorporating the same UK and European instruments deployed during THESEO.", "keywords": "UTLS, THESEO, balloon, chemistry", "status": "completed", "publicationState": "published", "identifier_set": [], "observationCollection": [ "https://api.catalogue.ceda.ac.uk/api/v2/observationcollections/4033/?format=api" ], "parentProject": "https://api.catalogue.ceda.ac.uk/api/v2/projects/2325/?format=api", "subProject": [], "responsiblepartyinfo_set": [ "https://api.catalogue.ceda.ac.uk/api/v2/rpis/55932/?format=api", "https://api.catalogue.ceda.ac.uk/api/v2/rpis/55931/?format=api" ] }, { "ob_id": 14406, "uuid": "4a03dbfb70584712bda1b87081a99196", "title": "AETIAQ - Aviation Emissions and Their Impact on Air Quality", "abstract": "The aim of AETIAQ was to broaden the currently sparse pool of data on the emission and evolution of exhausts from aircraft in their LTO cycle, so that predictive models of airport air quality can be validated and improved.

New, state of the art equipment was applied to measure the atmospheric mass budget and, in particular, the net export from the downwind coast over the UK. For the majority of the pollutants this is the dominant term and its measurement provides a very powerful test of current understanding of the processes and the current generation of long range transport models. The approach was applied to sulphur compounds, oxidized and reduced nitrogen, ozone and related photochemical oxidant precursors, mercury, a range of heavy metals and the main radiatively active gases. The analysis and interpretation of the data was completed using a range of current long range transport, transformation and deposition models.\r\n\r\nAMPEP was an aircraft measurement campaign using the FAAM BAe-146-301 and the flights were scheduled to take place between March and September 2005.", "keywords": "", "status": "completed", "publicationState": "published", "identifier_set": [], "observationCollection": [ "https://api.catalogue.ceda.ac.uk/api/v2/observationcollections/5905/?format=api" ], "parentProject": "https://api.catalogue.ceda.ac.uk/api/v2/projects/1345/?format=api", "subProject": [], "responsiblepartyinfo_set": [ "https://api.catalogue.ceda.ac.uk/api/v2/rpis/55955/?format=api" ] }, { "ob_id": 14414, "uuid": "e3a9ef59c39b41428d5d1dc36cd978ec", "title": "CLPX-II - Cold Lands Processes eXperiment Part 2", "abstract": "The objective is to understand the microwave radiative transfer and thermal signatures of snow packs.
