Data were collected by the Chilbolton Facility for Atmospheric and Radio Research (CFARR) Meteorological Sensor from 2001 to present at Chilbolton, Hampshire. The standard meteorological measurements are made at Chilbolton in support of all experiments at the Observatory. The data are automatically recorded every 10 seconds from a range of different sensors. The dataset contains measurements including temperature, dew point, pressure, wind speed and wind direction.

Single-polar products from the Met Office's Castor Bay C-band rain radar, Belfast, Northern Ireland. Data include CPAPR and augmented refractivity products from January 2013 and March 2011 respectively. The radar is a C-band (5.3 cm wavelength) radar and data are received by the Nimrod system at 5 minute intervals.

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) Present Weather Sensor from 21st of August 2009 to the present at Chilbolton, 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 Organisation) weather codes.

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.

Dual-polar products from the Met Office's Holehead C-band rain radar, Stirling, Scotland. 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 at present. The radar is a C-band (5.3 cm wavelength) radar and data are received by the Nimrod system at 5 minute intervals.

Single-polar products from the Met Office's Cobbacombe Cross C-band rain radar, Devon, England. Data include reflectivity (from August 2009), Doppler (from June 2008), CPAPR (from March 2011) and augmented refractivity (from March 2011) products. 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 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.

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.

2 km resolution data from the NIMROD system data describe rain-rate observations taken at Chenies, Herfordshire, England, by NIMROD, which is a very short range forecasting system used by the Met Office. 1 km rain rate data are available from 2004 until present. Radar images from the C-band (5.3 cm wavelength) radar are received by the Nimrod system 5 minute intervals respectively.
