Data were collected by Chilbolton Facility for Atmospheric and Radio Research (CFARR) Raingauges from 15th of March 2002 to the present at Sparsholt College, Hampshire. The dataset contains measurements of rainfall accumulation as measured by RAL Rapid Response Drop Counting rain gauges.
Measurements of troposhperic attenuation (excess and total) made at Sparsholt in Hampshire, UK using the ITALSAT satellite F1 beacon signal at 50 GHz. ITALSAT F1 (owned and operated by the Italian Space Agency) was in geostationary orbit at 13 degrees east, and it could be seen from the receiving station at an elevation angle of 30 degrees. The received signal was vertically polarised and was sampled once a second. North-south tracking of the satellite with the beacon receiver maintained ~20dB of dynamic range thought of the measurement period. The method applied to remove the nonatmospheric changes of the beacon signal and to establish the reference level from which to measure the excess and total attenuation is described in [Ventouras et.al., Long-term statistics of tropospheric attenuation from the Ka/U band ITALSAT satellite experiment in the United Kingdom, Radio Sci.,41,RS2007,doi:10.1029/2005RS003252]. The accuracy of fade level retrieval is estimated to be ~+/-0.5dB

Data from observations made using Chilbolton Facility for Atmospheric and Radio Research (CFARR).The Science and Technology Facilities Council (STFC) facility at Chilbolton Observatory, Hampshire (51.1445N, 1.4270W) is the home of many observation systems for meteorological and atmospheric science research. There are 4 radar systems designed to study precipitation, clouds and clear air, of which the largest is the 3 GHz Doppler radar (CAMRa) on the 25 m dish. There are also 4 lidar systems providing data on elastic backscattering, Doppler velocity, water vapour profiles and depolarisation. A wide range of meteorological and multiple raingauge data are available from both Chilbolton and the nearby Sparsholt field site. There is a wide range of radiometers at the site: microwave (for water vapour and liquid water measurements) and downwelling infra-red and visible detectors for radiation budget measurements. This dataset holds attenuation time-series data from vertically polarised 5 km links from South Wonston to Sparsholt. Cloud camera data from the Chilbolton site are available to provide visual information on weather conditions. CFARR is funded by the Natural Environment Research Council (NERC) and is owned and operated by the Space Science and Technology Department of the STFC.
The Sparsholt College-South Wonston water station radio links data describe signal levels of several links at a frequency of 56 Ghz, which covered a path of 5km from the South Wonston water tower near the A34 to Sparsholt College. The data were collected between October 2002 and April 2005. The radio link between Sparsholt college and the Wonston water tower is used to investigate the effects of rain and sleet on radio signals.
Data were collected from the 14th of February 2009 to the present by the Leosphere EZ polarization lidar at Chilbolton Observatory, Hampshire. The dataset contains plots of the attenuated backscatter coefficient at different heights, and of the depolarization ratio of particles. The dataset contains: Plots of the attenuated backscatter coefficient at different heights, and of the depolarization ratio of particles. Atmospheric backscatter light intensity (raw data) Solid angle and background calibrated data Vertical backscatter and extinction profile Vertical Aerosol profile Planetary Boundary Layer and residual layer heights Semi-transparent cloud height and top Optical depth integrated over whole Lidar range Dynamic structure of the atmosphere (e.g gravity waves...) Asphericity information on the particle in order to discriminate some particles from others (soil dust from other aerosol, ice/water phase of the clouds…)
Data were collected by the Chilbolton Facility for Atmospheric and Radio Research (CFARR) Infra-Red Radiometer from 10th of May 2001 to the present at Chilbolton, Hampshire. The dataset contains measurements for both sky and surface emitted infrared radiation, from 4.5 to 42 µm.
Sky images collected by a JVC KYF55-BE digital camera over Chilbolton, Hampshire. The data were collected from 5th of July 1996 to the present.
Data are of sky images collected by an AXIS 2100 digital camera over Chilbolton, Hampshire. The data collected are from 21st of January 2005 to the present and are available in avi movie files and tar files of jpeg images. Images are taken every 15 seconds.
Data were collected from the 12th of September 2006 to the 30th of June 2011 by the HALO photonics Doppler lidar at Chilbolton Observatory, Hampshire. The dataset contains measurements attenuated backscatter coefficients of aerosols within the atmosphere, as well as the radial and Doppler velocity of these particles. Plots of the attenuated backscatter coefficient at different heights, and of the Doppler velocity of particles are also available.
