The ANSTO dual-flow-loop two-filter works by removing all ambient radon (222Rn) and thoron (220Rn) progeny in the sampled air\r\n from the airstream using a filter before the air passes into a large delay volume to allow for the decay of the short-lived isotope 220Rn. The sample air in the\r\n detector is passed through a flow loop at a flow rate designed to exchange the delay volume's air in approximately 20 minutes. This allows time for new radon\r\n progeny to form. A second flow loop circulates the volume of the delay chamber through the second filter (a low-impedance 625 mesh stainless steel screen) to\r\n collect all 218Po progeny. The newly formed progeny are collected on the second filter and their decays are counted with a ZnS-photomultiplier system.

These systems were based on a 1565 nm laser emitting linearly polarised pulsed light through an 8 cm diameter lens with a heterodyne detector. Laser beam returns from the atmosphere are range-gated velocity and back-scattered power. The Halo systems are capable of full hemispheric scanning of the backscatter coefficient and radial velocity as a function of beam range.\r\n\r\nThe usual operation at Cardington was vertical stares (zenith angle=0°) with periodic wind scans that invoked various options of off-axis views. Wind profiles performed every 30 min was the default operation for wind scans. Most profiles of horizontal wind within the dataset are based on DBS (Doppler beam swinging) scans which use a tri-axis azimuthally orthogonal technique using the single lidar beam to retrieve horizontal mean wind components. This scan was chosen for the bulk of the time because it only takes about 21 s to complete, which leaves 98% of the available time to vertical stares if one wind scan is completed every 30 min. More recent scans in the dataset have used multi-axis VAD (velocity azimuth display) scans, which are a more involved version of the DBS scans and use 6 or 12 point off-zenith views.

It has Doppler and dual-polarisation capability. The radar measures the location and intensity of precipitation, radial winds and polarisation parameters. It works by transmitting pulses of electromagnetic radiation and measuring the amount of energy backscattered to the receiver. The time delay between the transmitted and received pulses enables the range of the object to be determined. In the case of precipitation, the magnitude of the backscattered signal is proportional to the size and number of raindrops. The radar also measures the radial velocity through the Doppler effect. In the absence of precipitation, the radar is sensitive to backscattering from insects, known as clear-air echoes, at close range. These signals provide information on the wind field and the organisation of the boundary-layer e.g. features such as convergence lines can be identified. In addition, the radar has dual-polarisation capability; it simultaneously transmits and receives horizontally- and vertically- polarised waves. Through this technique the radar measures a number of additional variables that provide information on the size and shape of precipitation, identification of non-meteorological echoes, attenuation (a decrease in the signal strength due to the absorption and scattering of the radar signal as it propagates through heavy rain), and alternative methods for calculating rainfall rates. \r\n\r\nThe system has a conventional parabolic antenna of 2.4m diameter and a beamwidth of 1 degree (in the horizontal and vertical), and is operated without a radome. The range resolution is tunable and dependent on the user-selected pulse width (0.5, 1 or 2 micro seconds) and pulse repetition frequency (PRF, 250-2000 Hz). The radar is fully transportable, being mounted on a trailer approved for EU roads that can be towed by a 4x4 vehicle. Signal analysis, data retrievals and data storage are performed by PCs contained within the trailer unit. The radar can be operated via a laptop that connects by wireless, ethernet or 3G to the onboard PCs. The operational software allows the user to set up the radar for deployment and schedule the scanning sequence. The software also provides real-time data visualisation and product generation.\r\n\r\nThe data frequency is dependant on the requirements for the instrument's deployment, but is typically of the order of 10 360-degree scans at various elevations every 5 minutes.\r\n\r\nParameters available in data files from this instrument include: \r\nDOP - degree of polarization; \r\nKDP - specific differential phase shift; \r\nPhiDP - differential phase shift; \r\nRhoHV - co-polar cross correlation coefficient; \r\nSQI - signal quality index or normalized_coherent_power; \r\nV - radial velocity; \r\nW - spectral width; \r\nZDR - differential reflectivity; \r\ndBZ - reflectivity or equivalent reflectivity factor." }, "relatedTo": { "ob_id": 43719, "uuid": "a9ea7a4d0c0742908eb256ac3134af30", "short_code": "acq", "title": "NCAS X-band Radar 1 at MOD Lyneham for WOEST", "abstract": "Scan data from the National Centre for Atmospheric Science Atmospheric Measurement and Observation Facility's mobile X-band radar unit 1 during the Wessex convection experiment Observing the Evolving Structures of Turbulence (WOEST) project." } }, { "ob_id": 14191, "platform": { "ob_id": 817, "uuid": "0d60dd064b6449b09f5c7fd4c41bd693", "short_code": "plat", "title": "NCAS Chilbolton Atmospheric Observatory (CAO)", "abstract": "The National Centre for Atmospheric Science's Chilbolton Atmospheric Observatory, formerly known as the Chilbolton Facility for Atmospheric and Radio Research (CFARR), is hosted by the Science and Technology Facilities Council (STFC) in rural Hampshire in the South of England.

The site was used as an airfield during the Second World War and is relatively flat and slightly elevated above the surrounding area.\r\n\r\nThe observatory operates more than twenty major instruments, many continuously, while others are available on-demand according to user configuration requirements. The portfolio includes a powerful combination of dual-polarisation Doppler radars, lidars, radiometers, and supporting instruments; the continuous round-the-clock operation of lidar and cloud radar instruments at Chilbolton is unique within the UK. These are supplemented by a suite of meteorological instrumentation including rain gauges, and disdrometers. A multi-wavelength sun photometer provides continuous measurements of aerosol optical depth in clear skies, and contributes to the Aerosol Robotic Network (AERONET).\r\n\r\nThe Chilbolton Advanced Meteorological Radar (CAMRa) is mounted on a 25-metre, fully steerable antenna, and is able to probe clouds and storms with unparalleled sensitivity and resolution. In addition, zenith-pointing polarimetric, Doppler 35 GHz and 94 GHz cloud radars are routinely operated for detailed microphysical studies of cloud processes and cloud climatology. A transportable, scanning 35 GHz cloud radar system is also hosted at Chilbolton, further enhancing the available capability.\r\n\r\nChilbolton was one of the pilot cloud profiling sites for the CLOUDNET project, and continues to make observations that feed into the Aerosol Clouds and Trace Gases Research Infrastructure (ACTRIS).

It is a clear-air UHF Doppler radar system operating at 1290 MHz to measure signal intensity and wind speed and direction under all weather conditions. At this frequency clear-air scattering (from refractive index inhomogeneities) dominates the radar signal return in the absence of hydrometeors, and the signal power is a measure of turbulent intensity. \r\n\r\nThe wind profiler consists of three panels to emit and receive three separate beams, a vertical beam from the central panel and two other beams orthogonal to the central beam at an elevation of 73 degrees to enable full wind vectors to be calculated. Each panel is an array of eight aerials, each consisting of an assembly of eight collinear dipoles. \r\n\r\nThe radar is usually operated in two modes: a low altitude mode with a 1000 ns pulse and a high altitude mode with a 2500 ns pulse. The radar typically returns wind profiles from around 100 to 2500 m and can be used to measure the depth of the convective boundary layer and the position of atmospheric convective \"lids\".
