Data were collected from the 4th of April 2002 to the present by the Ultra-violet Raman lidar at Chilbolton Observatory, Hampshire. The dataset contains measurements of attenuated backscatter coefficients of aerosols within the atmosphere, and a full Doppler spectrum, and moments Z, v, and w.

The Sparsholt College-South Wonston water station radio links data describe signal levels of several links at a frequency of 54 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) Visible Radiometer from 10th of May 2001 to the present at Chilbolton, Hampshire. The dataset contains measurements of high accuracy total global, or diffuse sky, solar radiation measurement research on a plane/level surface, for extreme temperature environments.

The GBS (Global Broadcast Service) dataset is a series of radio attenuation measurements made at three sites in the UK: Chilbolton and Sparsholt, both in southern UK, and Dundee in Scotland. The aim of the experiment was to make long term measurements of the signal strength received from a 20.7GHz beacon on the US Department of Defense satellite UFO-9 at multiple sites, in order to determine whether the use of site diversity as a fade mitigation technique would be effective. The dataset spans a period of 3 years, from August 2003 to August 2006 with signal attenuation sampled once per second. This dataset is cited in: S. A. Callaghan, J. Waight, J.L.Agnew, C. J. Walden, C.L.Wrench , S. Ventouras “The GBS dataset: measurements of satellite site diversity at 20.7 GHz in the UK”, Geoscience Data Journal, 17 March 2013, DOI: 10.1002/gdj3.2

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.

The International Satellite Land Surface Climatology Project, Initiative II (ISLSCP II) is a follow on project from The International Satellite Land Surface Climatology Project (ISLSCP). ISLSCP II had the lead role in addressing land-atmosphere interactions - process modelling, data retrieval algorithms, field experiment design and execution, and the development of global data sets. The ISLSCP II dataset contains comprehensive data over the 10 year period from 1986 to 1995, from the International Satellite Land Surface Climatology Project (ISLSCP). This dataset contains: *Sea-Air CO2 Flux and Sea-Air CO2 Partial Pressure *CO2 Consumption by Continental Erosion and Riverine Fluxes of Carbon and Sediments to the Oceans *CO2 Emissions *Energy Flux Measurement *Atmospheric CH4 Data *Atmospheric CO2 Data *Global Net Primary Productivity The data are mapped to consistent grids (0.5 x 0.5 degrees for topography, 1 x 1 degrees for meteorological parameters). Some data have a grid size of 0.25 x 0.25 degrees. The temporal resolution for most data sets is monthly (however a few are at finer resolution - 3 hourly). This dataset is public.

Data were collected from the 31st of March 2004 to the 29th of March 2011 by the Copernicus Doppler cloud radar at Chilbolton Observatory, Hampshire. The dataset contains measurements of attenuated backscatter coefficients of aerosols within the atmosphere, and a full Doppler spectrum, and moments Z, v, and w.

Data from the Along Track Scanning Radiometer (ATSR) instrument on the ERS-2 platform operational between 1995 and 2011. The ATSR is an imaging radiometer providing images of the Earth from space on the ERS2- platform. The ERS (Earth Resources Satellite) programme was funded by and operated by ESA and was the first main ESA EO data campaign. ATSR-1 was placed on the ERS-1 platform and ATSR-2 was on the ERS-2 platform. The ATSR-1 and 2 instruments were followed by the Advanced Along Track Scanning Radiometer (AATSR) on the ENVISAT platform in 2002. The ATSR-2 instrument has been designed for exceptional sensitivity and stability of calibration, which are achieved through the incorporation of several innovative features in the instrument design. This design has, among other things, enabled the accurate measurement of sea surface temperature to an accuracy of +/- 0.3K. The design of the ATSR instrument incorporates a dual view made possible by the rotating scan mirror. There is a nadir view and then a subsequent along track view. These provide 2 images per scan and allow improved estimate of atmospheric attenuation. This coupled with the inclusion of consistent calibration using on-board black bodies allows for the collection of extremely radiometrically accurate data. The data are Level1 Ungridded Brightness Temperatures (UBT). The data are in SADIST-2 format and CEDA is the primary archive for this data. The UBT product provides scenes for both nadir and forward views with a swath width of 512km and a ground pixel distance of 1km. This dataset is superceded by the AATSR Multimission ATSR-2 data set that involved reprocessing this data with improved calibration and cloud masking and is available in a number of reprocessings so consistent with ENVISAT format data.

Data were collected by the Chilbolton Facility for Atmospheric and Radio Research (CFARR) Radiometrics Radiometer from the 23rd of August 2007 to the present at Chilbolton, Hampshire. The dataset contains measurements of the total liquid water at zenith, together with the vertical profile of water vapour density. Accuracy of integrated water vapour (IWV) retrieval: ~1 – 2 mm Accuracy of total liquid water path (LWP) retrieval: ~15% in non-precipitating conditions.
