Dual-polar products from the Met Office's Hill of Dudwick C-band rain radar, Aberdeenshire, Scotland. Data include augmented ldr and zdr scan data (both long and short pulse). The radar is a C-band (5.3 cm wavelength) radar and data are received by the Nimrod system at 5 minute intervals.

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 METAR reports describe hourly observations from 562 observation stations across the globe, including 131 UK stations. The data are produced by Synoptic observations for aviation purposes, giving measurements of parameters such as cloud amount, wind speed and direction, visibility, present weather, and maximum gust speed. The data are collected by observation stations worldwide and transmitted within the METAR message.

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.

TEMP records describes measurements reported up to four times daily by radiosondes at worldwide fixed land stations. The radiosondes measure parameters such as atmospheric pressure, temperature, humidity, and wind speed and direction. The data are measured from the surface to approximately 20-30 km, and measurements are usually taken every 2 seconds. These data are provided from the Met Office as-is requiring each message part to be brought together to form each profile.

Dual-polar products from the Met Office's Clee Hill C-band rain radar, Shropshire, England. Data from this site include augmented ldr (linear depolarisation ratio) and zdr (differential reflectivity) scan data (both long and short pulse), available from August 2018 to present. The radar is a C-band (5.3 cm wavelength) radar and data are received by the Nimrod system at 5 minute intervals.

1 km resolution rain rate data from Met Office's Predannack C-band rain radar, Cornwall, England as part of the NIMROD, very short range forecasting system used by the Met Office. 1 km rain rate data are available from 2011 until present. Radar images from the C-band (5.3 cm wavelength) radar are received by the Nimrod system 5 minute intervals respectively.

Single-polar products from the Met Office's Hameldon Hill C-band rain radar, Lancashire, England. Data include reflectivity and augmented Doppler products from June 2005 and December 2012 respectively. The radar is a C-band (5.3 cm wavelength) radar and data are received by the Nimrod system at 5 minute intervals.

The Campbell Scientific PWS100 present weather sensor deployed at the Chilbolton Observatory, Hampshire, detects and classifies precipitation by observing the scattering of a laser beam 20 degrees off the forward direction in the horizontal and vertical planes. The detected signals depend on the size, shape, optical properties, concentration and velocity of the particles. The instrument is mounted approximately 10m above ground on the roof of a cabin at the Chilbolton Observatory site. It is operated continuously. Data include: counts as a function of size of hydrometeors in 300 bins from 0.1 to 30.0 mm, the number of hydrometeors in 9 type categories. visibility, air temperature, relative humidity, rainfall rate, rainfall accumulation, average hydrometeor velocity, average hydrometeor size and reports the World Meteorological Organisation (WMO) present weather code for the site. Data are archived as netCDF files.

Single-polar products from the Met Office's Holehead C-band rain radar, Stirling, Scotland. Data include reflectivity (from April 2012), Doppler (from August 2012) and CPAPR (from August 2012) products. The radar is a C-band (5.3 cm wavelength) radar and data are received by the Nimrod system at 5 minute intervals.
