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) 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.

Radio propagation measurements at 40 GHz at Chilbolton, Hampshire for the ESA funded Large Scale Assessment of KA/Q band atmospheric channel using the ALPHASAT TDP5 Propagation beacon signal.

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.

Radio propagation measurements at 20 GHz at Chilbolton, Hampshire for the ESA funded Large Scale Assessment of KA/Q band atmospheric channel using the ALPHASAT TDP5 Propagation beacon signal.

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 Chilbolton Facility for Atmospheric and Radio Research (CFARR) Raingauges from 1st of May 1995 to the present at Chilbolton, Hampshire. The dataset contains measurements of rainfall accumulation as measured by RAL Rapid Response Drop Counting rain gauges.

Data were collected by Chilbolton Facility for Atmospheric and Radio Research (CFARR) Raingauges from 2001 to the present at Chilbolton, Hampshire. The dataset contains measurements of rainfall accumulation as measured by multiple instruments.

Data were collected by Chilbolton Facility for Atmospheric and Radio Research (CFARR) Raingauges from 1st of July 2004 to the present at Sparsholt College, Hampshire. The dataset contains measurements of rainfall accumulation as measured by multiple instruments.

The Chilbolton Observatory, Hampshire, have had a Vaisala CT75K lidar ceilometer deployed since 13th September 1996. This dataset contains measurements of the range of first, second, and third cloud base from the lidar and attenuated backscatter coefficients of aerosols within the atmosphere from 1996 to 2013. Plots of the attenuated backscatter coefficient at different heights are also available. The instrument has been regularly calibrated using the method described by O'Connor, Ewan J., Anthony J. Illingworth, Robin J. Hogan, 2004: A Technique for Auto-calibration of Cloud Lidar. J. Atmos. Oceanic Technol., 21, 777–786. doi: http://dx.doi.org/10.1175/1520-0426(2004)021<0777:ATFAOC>2.0.CO;2 . Prior to April 2014 this technique had been applied manually, but from 2014 this was automated to provide a routine, automated application of O'Connor et al's calibration technique. This also highlighted an instrument calibration drift not previously spotted in earlier data and so a corrected data have been added to the archive for the following periods (denoted by "_cor1" in the filename): 1st July 2003 – 31st December 2003, January 2006 to December 2012 and February and March 2013. Users should see the data quality notes for further details. For post 2013 data please refer to the "all-years" dataset.
