            "title": "Climatic Research Unit (CRU) procedure to produce the CRU JRA v2.4 data.",
            "abstract": "The CRU JRA (Japanese reanalysis) data is a replacement to the CRU NCEP dataset, CRU JRA data follows the style of Nicolas Viovy's original dataset rather than that which is available from UCAR.\r\n\r\nThe CRU JRA dataset is based on the JRA-55 reanalysis dataset and aligned where appropriate with the CRU TS dataset version 4.07 (1901-2022).\r\n\r\nAll JRA variables are regridded from their native TL319 Gaussian grid to the CRU regular 0.5° x 0.5° grid, using the g2fsh spherical harmonics routine from NCL (NCAR Command Language), based on the 'Spherepack' code. The exception is precipitation, which is regridded using ESMF 'nearest neighbour': all other algorithms tried exhibited unwanted artifacts.\r\n\r\nThe JRA-55 reanalysis dataset starts in 1958. The years 1901-1957 are constructed using randomly-selected years between 1958 and 1967. Where alignment with CRU TS occurs, the relevant CRU TS data is used.\r\n\r\nOf the ten variables listed above, the last four do not have analogs in the CRU TS dataset. These are simply regridded, masked for land only, and output as CRUJRA. The other six are aligned with CRU TS as follows:\r\n\r\nTMP is aligned with CRU TS TMP. A monthly mean for the JRA data is\r\ncalculated and compared with the equivalent CRU TS mean. The difference\r\nbetween the means is added to every JRA value.\r\n\r\n---\r\n\r\nTMAX and TMIN are aligned with CRUJRA TMP and CRU TS DTR. Firstly, at\r\neach time step, the TMAX-TMP-TMIN triplets are checked and adjusted so\r\nthat TMAX is always >= TMP, and TMIN is always <= TMP. This triplet\r\nalignment is prioritised above DTR alignment. Secondly, monthly JRA DTR\r\nis calculated by first establishing the daily maxima and minima (max and\r\nmin of the subdaily values in TMAX and TMIN respectively), then monthly\r\nmaxima and minima, (means of the daily DTR values), giving JRA monthly\r\nDTR. This is compared with CRU TS DTR and the fractional difference\r\n(factor) calculated as (CRU TS DTR) / (JRA monthly DTR). This factor is\r\nthen used to adjust the DTR of each pair of subdaily TMAX and TMIN\r\nvalues, though not if the triplet alignment would be broken.\r\n\r\n---\r\n\r\nPRE is aligned with CRU TS PRE and WET (rain day counts). Firstly, the\r\nmonthly total precipitation is calculated for JRA and compared to CRU TS\r\nPRE; an adjustment factor is acquired (crupre/jrapre) and all values\r\nadjusted. Precipitation amounts are now aligned at a monthly level, and\r\nthis alignment is prioritised above WET alignment. Secondly, the number\r\nof rain days is calculated for JRA: a day is declared wet if the total\r\nprecipitation is equal to, or exceeds, 0.1mm (the same threshold as CRU\r\nTS WET). If JRA has more wet days than CRU TS, then the driest of those\r\nare reduced to a random amount below 0.1 (an adjustment factor is\r\ncalculated and applied to each time step, to preserve the subdaily\r\ndistribution). If JRA has fewer wet days than CRU TS, then sufficient\r\ndry days are set to a random amount equal to or closely above 0.1mm,\r\nagain using an adjustment factor to preserve the subdaily distribution. \r\nWhere wet day alignment threatens precipitation alignment, the process\r\nis abandoned and the cell/month reverts to the previously-aligned\r\nprecip version. Exception handling is very complicated and cannot be\r\nsummarised here.\r\n\r\n---\r\n\r\nSPFH is aligned with CRU TS VAP. VAP is converted to SPFH, and JRA mean\r\nmonthly SPFH is calculated. The fractional difference (factor) is\r\ncalculated as (CRU TS SPFH) / (JRA monthly SPFH), this factor is then\r\napplied to the JRA subdaily humidity values.\r\n\r\n---\r\n\r\nDSWRF is aligned with CRU TS CLD. CLD is converted to shortwave\r\nradiation, and JRA mean monthly DSWRF is calculated. The fractional\r\ndifference (factor) is calculated as (CRU TS SWR) / (JRA monthly DSWRF),\r\nthis factor is then applied to the JRA subdaily radiation values.\r\n\r\n---\r\n\r\nWhere appropriate, CRUJRA values are kept within physically-appropriate\r\nconstraints (such as negative precipitation), which could result from\r\nregridding as well as adjustments.",

MERIS and SPOT-VGT level-1 data serves as input data to a processing chain. The function of the processing chain can be summarised as:\r\n processes every single input to some level in several processing steps.\r\n accumulates at least one year of data for each 10º x 10º tile and then calculates products every 8 days as well as every month, as well as seasonal and annual products.\r\n finally retrieves BRDF and albedo for each composite reporting time-step (every 8 days and every month, as well as seasonal and annual products).\r\nFirstly, all inputs are systematically processed from L1 to surface directional reflectances\r\n(SDR). The processing steps to retrieve SDRs are:\r\n pixel classification for cloud, water, etc.. detection\r\n retrieval of aerosol optical thickness\r\n atmospheric correction using retrieved aerosol optical thickness\r\nThe results are SDR values in the same granularity as the inputs. They are not written for distinct products, but just kept in memory and used as input to the next part of the processing chain. The processing steps are\r\n broad-band integration of these SDRs\r\n re-projection of these broad-band SDRs onto the MODIS Sinusoidal grid\r\nThe results of this step are re-projected broadband directional reflectances (BBDR) still in the granularity of the input products. During implementation, it has been decided to store this intermediate product of BBDR tiles on disk, but to remove them subsequently after the BRDF computation (accumulation/inversion). The steps are:\r\n computation of BRDFs every 8-days and every month of the broad-band BBDRs from all sensors by accumulation method, using an additional land cover mask information from Idepix\r\n computation of the albedo from these BRDFs\r\nThe final results are 8-day, monthly, seasonal, and annual composites of broadband\r\nalbedo. \r\nFor more information on the processing please see the product user guide and the ATBD in the docs tab.",

The first ingests the Edition 1 GERB HR OLR data and generates an area weighted flux product at 1° by 1° spatial resolution for every 15-minute time interval. In the second stage these data are averaged over time to produce an hourly averaged product. Each hour interval is defined as the time-centred mean at half-past the hour, e.g. 1030 UTC, comprises the mean of data from 1000 UTC, 1015 UTC, 1030 UTC and 1045 UTC (or from those slots in this window that are available). An hourly average is produced for a 1° by 1° grid cell if there is at least one of the four observation times available for that grid cell. If no available data are available for a particular hour of a day, then the third stage is implemented, and these hours are filled using broadband fluxes derived from the narrowband SEVIRI data corrected to the GERB observations at the monthly hourly 1° scale1. The final processing stage averages the hourly mean fluxes over the days in the month to produce a one degree monthly hourly mean product. The number of filled data points (days per monthly hourly mean) contributing to each monthly mean are used to estimate the uncertainties associated with the product.

            "abstract": "The GERB TOA reflected shortwave radiation (RSW) Obs4MIPs product has been generated from GERB level 2 HR RSW fluxes. There are five main stages. The first is to take the Edition 1 GERB HR SW flux data with the user corrections applied and generate an albedo using knowledge of the incoming SW flux for each location and time. The albedo is then area weighted to create a 1° by 1° spatial resolution albedo for every 15-minute time interval. These data are then averaged over time to produce an hourly averaged albedo product for each hour of each day. Each hour interval is defined as the time-centred mean at half-past the hour, e.g. 1030 UTC comprises the mean of albedos from 1000 UTC, 1015 UTC, 1030 UTC and 1045 UTC (or from those slots in this window that are available). An hourly average albedo is produced for a 1° by 1° grid cell if there is one or more observation from the four observation times available for that grid cell. The averaged albedos are converted back to RSW flux using the incoming solar flux at the midpoint of the hour and 1° cell. The fourth stage identifies days where there are no observations available for the hour and fills them with broadband RSW fluxes derived from the narrowband SEVIRI data, averaged to the daily hourly scale in the same way as the GERB data and corrected to the GERB observations at the monthly hourly 1° scale1. Finally, a monthly mean for each hourly time step is calculated encompassing the full data. The number of filled data points (days per monthly hourly average) contributing to each monthly hourly mean are used to estimate the uncertainties associated with the product.

The\r\nmethod involves separating the radar echoes returning from the ice floes from those\r\nreturning from the sea surface in the leads between the floes. This step of a surface-type\r\nclassification is crucial and allows for a separate determination of the ice floe and\r\nsea-surface heights. The freeboard that is the elevation of the ice upper side (or ice/snow\r\ninterface) above the sea level can then be computed by deducting the interpolated\r\nsea-surface height at the floe location from the height of the floe. Sea-ice thickness can then\r\nbe calculated from the sea-ice freeboard with the additional information of the snow load.",

Since ground temperature  and  thaw  depth  cannot be  directly  observed  from  space-borne  sensors,  a  variety  of satellite  and  reanalysis  data  are  combined  in  a  ground  thermal  model.  The algorithm uses remotely sensed data sets of Land Surface Temperature (MODIS LST/ ESA LST CCI) and landcover (ESA Landcover CCI) to drive the transient permafrost model CryoGrid, which yields thaw depth and ground temperature at various depths, while ground temperature forms the basis for permafrost fraction. The Land Surface Temperature data sets are employed to determine the upper boundary condition of the differential equation, while its coefficients (e.g. heat capacity and thermal conductivity) are selected according to the landcover information (Westermann et al., 2017). With this, a spatial resolution of the final product of 1 km is possible, corresponding to “breakthrough” according to the WMO OSCAR database.\r\n\r\nInput data: MODIS Land surface temperature is used as the main input for the L4 production for 2003-2021 data. Sensors of auxiliary data are listed in the meta data.\r\nDownscaled and bias corrected ERA reanalyses data based on statistics of the overlap period between ERA reanalysis and MODIS LST are used for data before 2003.

Wind-driven rain is only calculated if the wind would strike a given wall orientation. A wind-driven rain spell is defined as a wet period separated by at least 96 hours with little or no rain (below a threshold of 0.001 litres per m2 per hour).\r\n\r\nThe annual index of wind-driven rain is calculated for a baseline (historical) period of 1981-2000 (corresponding to 0.61°C warming) and for global warming levels of 2.0°C and 4.0°C above the pre-industrial period (defined as 1850-1900). The warming between the pre-industrial period and baseline is the average value from six datasets of global mean temperatures available on the Met Office Climate Dashboard: https://climate.metoffice.cloud/dashboard.html.\r\n\r\nThe magnitudes of 1 in 3 year wind-driven rain spells (i.e. wet spells that would be expected to occur, on average, once every three years) were calculated for the baseline period (1981-2000) and 20-year periods corresponding to 2°C and 4°C of warming. The magnitudes of all wet spells (here, sum of hourly values of the wind-driven rain metric, I) were calculated, and the largest wet spell in each year was found (in the accompanying report, the magnitude of a wet spell is given the symbol Is' [\"Is prime\"] and has units of litres per metre-squared per spell). For each time period, the largest spells in all years and ensemble members were pooled together. A Gumbel distribution was fitted to the pooled data and used to estimate the magnitude of the 1 in 3 year wet spells across the UK.",

            "abstract": "The snow_cci SWE product has been based on the ESA GlobSnow SWE retrieval approach (Takala et al. 2011). The retrieval is based on passive microwave radiometer (PMR) data considering the change of brightness temperature due to different snow depth, snow density, grain size and more. The retrieval algorithm handles data from the sensors SMMR, SSM/I, SSMIS, AMSR-E and AMSR-2. The retrieval methodology combines the satellite passive microwave radiometer (PMR) measurements with ground-based synoptic weather station observations by Bayesian non-linear iterative assimilation. A background snow-depth field from re-gridded surface snow-depth observations and a passive microwave emission model are required components of the retrieval scheme. The GlobSnow algorithm implemented for snow_cci version 3 includes the utilisation of an advanced emission model with an improved forest transmissivity module and treatment of sub-grid lake ice. Because of the importance of the weather station snow-depth observations on the SWE retrieval, there is improved screening for consistency through the time series.\r\n\r\nPassive microwave radiometer data are obtained from the recalibrated enhanced resolution CETB ESDR dataset (MEaSUREs Calibrated Enhanced-Resolution Passive Microwave Daily EASE-Grid 2.0 Brightness Temperature (CETB) Earth System Data Record (ESDR) https://nsidc.org/pmesdr/data/) Algorithm improvements relative to snow_cci v2.0 include improved dry snow detection due to an update of the dry snow detection algorithm, improved SWE retrieval due to implementation of dynamic snow densitites into the retrieval, and improved snow masking, due to an update of the snow mask used for post-processing. The time series has been extended from snow_cci version 2 by two years with data from 2020 to 2022 added.\r\n\r\nSWE products are based on SMMR, SSM/I and SSMIS passive microwave radiometer data for non-alpine regions of the Northern Hemisphere.",

            "abstract": "The C3S: Obs4MIPs format GOME-type Total Ozone Essential Climate Variable (GTO-ECV), Version 9.0 dataset was generated by combining measurements from several nadir-viewing satellite sensors (GOME/ERS-2, SCIAMACHY/Envisat, OMI/Aura, GOME-2/MetOp-A, GOME-2/MetOp-B, TROPOMI/Sentinel-5P, and GOME-2/MetOp-C) into one single cohesive record.   This was done using a merging approach developed in the framework of the European Space Agency's (ESA's) Climate Change Initiative Ozone project.   Firstly, the separate pixel-based level-2 observation - produced by the GOME-type Direct FITting v4 retrieval algorithm (GODFIT) are converted into level-3 products per sensor i.e. daily and monthly averages on a regular grid of 1x1 degree in latitude and longitude.  Before the individual level-3 data records are finally merged into one single product, adjustments are applied in order  to minimize possible inter-sensor biases and/or temporal drifts. Due to its notable long-term stability one sensor (OMI/Aura) was selected to serve as a reference for the other instruments,  which are then adjusted in terms of a correction that depends on latitude and time. A detailed description of the merging approach, the generation, and the geophysical validation of GTO-ECV is provided in Coldewey-Egbers et al. (2015, 2022), Garane et al. (2018) and Lambert et al.

Water areas are masked if more than 30 percent of the pixel is classified as water, permanent snow and ice areas are masked if more than 50 percent are identified as such areas in the aggregated map. A new mask for salt lakes derived from manual delineation based on Terra MODIS data is added in the version 3.0 products from Terra MODIS. The product uncertainty for observed land pixels is provided as unbiased root mean square error (RMSE) per pixel in the ancillary variable and has been adjusted to account for updates in the retrieval algorithm. Two additional variables are provided for each daily product: the sensor zenith angle per pixel in degree, and the acquisition time per pixel referring to the scan line time of the MODIS granule used for the classification.",

            "abstract": "Based on the EUMETSAT AVHRR GAC FDR (Global Area Coverage), released in May 2023, a time series (1979–2022) was generated utilising the SCAmod algorithm of Metsämäki et al. (2015). Cloud masking relies on the probability mask of CLARA-A3, an upgrade of the existing cloud albedo and radiation (CLARA) data record developed and generated by EUMETSAT CM SAF, SMHI, which has also been produced from this FDR. \r\n\r\nAs a pre-condition, (FSC (NDSI) > 5%) was implemented based on Normalized Difference Snow Index (NDSI) calculations (Salomonson and Appel, 2006) before utilising the SCAmod algorithm (Metsämäki et al. 2015) for viewable snow (SCFV) and snow on ground (SCFG). A pre-classification was implemented to minimise erroneous results (solar zenith angle > 88°; cloud probability > 80%; water if percentage of pixel > 50; and permanent ice if percentage of pixel > 50). In addition, two thresholds were included to test whether a pixel potentially is snow free or snow covered (snow free if channel 1 > 0.12 or channel 4 > 283 K).  \r\n\r\nIn addition, different post-processing steps were implemented to improve the quality of the snow products: for latitudes ±15° and elevations below 1000 m a.s.l. a test was added (channel 1 < 0.30 or channel 4 > 270 K) to remove erroneous data in the tropical regions. A second test considers channel 3b: (channel 1 – channel 3b ≥ 0.2 and channel 3b < 0.1) for the Southern Hemisphere to remove erroneous snow pixels, with an additional adaptation for the globe (channel 1 – channel 3b < 0.1 and channel 3b < 0.2). The erroneous snow pixels with (channel_3a(/b)/channel_1 > 1 and channel_3a(/b)/channel_1 > 1) or (channel_2/channel_1 < 0.999 and channel_4 > 274 K) was removed. Additionally, the pixels with high solar zenith angle (VZA > 75°) and NDSI < 0.5 was removed. Some other criteria were also added in post-processing steps.",
