Data from the Upper Troposphere Lower Stratosphere (UTLS) programme's round 1 research project "Dynamics and Chemistry of Frontal Zones" (DCFZ). DCFZ investigated the role of frontal shear zones in determining upper tropospheric chemical distributions. This dataset contains Chilbolton radar images.

The Convective Storm Initiation Project (CSIP) aimed to further the understanding of the mechanisms responsible for the initiation of precipitating convection in the maritime environment of southern England; i.e. to understand why convective clouds form and develop into precipitating clouds in a particular location. Data have been collected from the 6th July 2004 to the 29th July 2004 by the Ultra-violet Raman lidar at Chilbolton Observatory, Hampshire. The dataset contains measurements of attenuated backscatter coefficients of aerosols within the atmosphere, and humidity mixing ratios. Plots of the attenuated backscatter coefficient, and of the humidity mixing ratios, at different heights are also available.

The Cloud and Water Vapour Experiment (CWAVE) was a measurement campaign at the CCLRC-Chilbolton Observatory; it was supporting associated with two EC FP5 projects, CLOUDMAP2 and CLOUDNET. A wide range of satellite and ground based instruments measured a variety of atmospheric properties ranging from cloud parameters to water vapour. In addition, the measurements coincided with the results from a reduced resolution Unified Model (UM) run by the Met Office.

The University of Leeds radiosonde data contain measurements collected by a radiosonde at Archern and Hornisgrinde, Germany from the 19th of April 2007 to the 30th of August 2007. The dataset contains measurements of air temperature, air pressure, wind speed and wind direction, and relative humidity. The dataset contains the following measurements: Scaled logarithmic pressure (4096 * ln P) Air temperature (K Relative humidity (percent) Northward wind (m s-1) Eastward_wind (m s-1) Altitude (m) Air pressure (hPa) Dew point temperature (K) Humidity mixing ratio (g/kg) Wind from direction (degree) Wind speed (m s-1) Sonde azimuth (degree) Sonde distance (m) Longitude (degree_east) Latitude (degree_north)

The data were collected by a Doppler Sodar, operated by the University of Leeds, at Barongartenhuette near Enzklosterle, Germany. The data provided are 15 minute averages of backscatter, horizontal wind and vertical wind. The dataset contains the following measurements: Wind speed Wind direction Eastward wind Backscatter Upward air velocity Height Northward wind

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.

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.

The Sparsholt College-South Wonston water station radio links data describe signal levels of several links at a frequency of 38 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.
