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 38 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 by the Chilbolton Facility for Atmospheric and Radio Research (CFARR) Present Weather Sensor from 28th of January 2005 to the 21st of May 2007 at Sparsholt College, Hampshire. The dataset contains reports of current weather conditions and those over the last hour using both NWS (National Weather Service)and WMO (World Meteorological Organistion) weather codes.

Raw beacon radio propagation measurements at 20 and 40 GHz (KA/Q bands) made at Chilbolton, Hampshire, UK, for the ESA funded 'Large Scale Assessment of KA/Q band atmospheric channel using the ALPHASAT TDP5 propagation beacon signal (ASALASCA)' project. These are signals measured by the two receivers located at Chilbolton received from the Aldo Paradoni Payload (TDP5) beacon on board ESA's ALPHASAT telecommunications satellite. Measurements began in July 2016.

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 by the Chilbolton Facility for Atmospheric and Radio Research (CFARR) Visible Radiometer from 10th of May 2001 to the present at Chilbolton, Hampshire. The dataset contains measurements of Calibrated brightness temperature measured at 21 frequencies (selectable) between 22.0 and 30.0 GHz, water vapour profile, and integrated water vapour (IWV). Data are produced once every approximately 2 minutes.

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.

Data were collected by the Chilbolton Facility for Atmospheric and Radio Research (CFARR) Disdrometer from the 1st of April 2003 to the present at Chilbolton, Hampshire. The dataset contains measurements of the drop size distribution of rain.

Data were collected by the Chilbolton Facility for Atmospheric and Radio Research (CFARR) Disdrometer from the 1st of July 2004 to the present at Sparsholt College, Hampshire. The dataset contains measurements of the drop size distribution of rain.
