  • 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 Deanhill C-band rain radar, Whiltshire, England. Data include reflectivity and augmented Doppler products from April 2012 and June 2008 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.

  • 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. 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. This dataset incorporates the earlier published and citable 1996 - 2013 collection of lidar data, but continues this dataset to present

  • Earth-system modelling data from the UK-Japan Climate Collaboration (UJCC). The project is a joint project between the Hadley Centre (DEFRA) and the NCAS-CGAM (Centre for Global Atmospheric Modelling) at the University of Reading. UJCC makes use of a broad group of models in order to systematically explore the role and value of resolution in climate system research. The dataset comprises of UJCC 30 year simulations from models at resolutions of either (1.25 lat x 1.875 lon) or (0.83 lat x 1.25 lon) with differing degrees of atmosphere-ocean coupling (1 degree ocean or 1/3 degree ocean). The dataset also includes NUGAM (Nihon-UK Global Environmental Model) Atmosphere only simulations and NUGEM Coupled atmosphere and ocean simulations which are both at the same resolution (0.83 lat x 0.56 lon, corresponding to ~60 km in mid-latitudes).

  • 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.

  • Data were collected by the Chilbolton Facility for Atmospheric and Radio Research (CFARR) Meteorological Particle Sensor from 2009 to present. During this time the particle sensor was at Chilbolton, Hampshire, whilst previously it had been positioned at Sparsholt College, Hampshire. The dataset contains measurements of the size of individual particulates including rain, snow, and hail, as well as estimates of drizzle, total rainfall and liquid water content.

  • Dual-polar products from the Met Office's Castor Bay C-band rain radar, Belfast, Northern Ireland. 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.

  • Dual-polar products from the Met Office's Munduff Hill C-band rain radar, Glenrothes, Fife, Scotland. Data include augmented refractivity data from June 2014. The radar is a C-band (5.3 cm wavelength) radar and data are received by the Nimrod system at 5 minute intervals.

  • 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.
