  • Data were collected from the 1st of November 2006 to the 31st of October 2010 by the HALO photonics Doppler lidar at Chilbolton Observatory, Hampshire. The dataset contains measurements attenuated backscatter coefficients of aerosols within the atmosphere, as well as the radial and Doppler velocity of these particles. Plots of the attenuated backscatter coefficient at different heights, and of the Doppler velocity of particles are also available.

  • Raw beacon radio propagation measurements at 20 and 40 GHz (KA/Q bands) made at Chilton, Oxfordshire, UK, for the ESA funded Large Scale Assessment of KA/Q band atmospheric channel using the ALPHASAT TDP5 Propagation beacon signal (ASALASCA) project. These are signals measured by the two receivers located at Chilbolton received from the Aldo Paradoni Payload (TDP5) beacon on board ESA's ALPHASAT telecommunications satellite. Measurements were made from July 2016 to present.

  • Data were collected by the Chilbolton Facility for Atmospheric and Radio Research (CFARR) Disdrometer from the 1st of April 2003 to the present at Chilbolton, Hampshire. The dataset contains measurements of the drop size distribution of rain.

  • 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

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

  • Data were collected from the 14th of February 2009 to the present by the Leosphere EZ polarization lidar at Chilbolton Observatory, Hampshire. The dataset contains plots of the attenuated backscatter coefficient at different heights, and of the depolarization ratio of particles. The dataset contains: Plots of the attenuated backscatter coefficient at different heights, and of the depolarization ratio of particles. Atmospheric backscatter light intensity (raw data) Solid angle and background calibrated data Vertical backscatter and extinction profile Vertical Aerosol profile Planetary Boundary Layer and residual layer heights Semi-transparent cloud height and top Optical depth integrated over whole Lidar range Dynamic structure of the atmosphere (e.g gravity waves...) Asphericity information on the particle in order to discriminate some particles from others (soil dust from other aerosol, ice/water phase of the clouds…)

  • 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.

  • Data were collected by the Chilbolton Facility for Atmospheric and Radio Research (CFARR) Meteorological Particle Sensor between 2004 and 2007. During this time the particle sensor was at Sparsholt College, Hampshire, after which it was re-located to Chilbolton. 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.

  • 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.

  • Sky images collected by a JVC KYF55-BE digital camera over Chilbolton, Hampshire. The data were collected from 5th of July 1996 to the present.
