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 13th June 2005 to the 25th August 2005 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.

Data were collected from the 4th of April 2002 to the present by the Ultra-violet Raman lidar at Chilbolton Observatory, Hampshire. The dataset contains measurements of attenuated backscatter coefficients of aerosols within the atmosphere, and a full Doppler spectrum, and moments Z, v, and w.

The data were collected by a Doppler Sodar, operated by the University of Leeds, at Achern, 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) 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 from the 31st of March 2004 to the 29th of March 2011 by the Copernicus Doppler cloud radar at Chilbolton Observatory, Hampshire. The dataset contains measurements of attenuated backscatter coefficients of aerosols within the atmosphere, and a full Doppler spectrum, and moments Z, v, and w.

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

The Icelandic Volcano, Eyjafjallajokull, started erupting on 14th April 2010. The volcanic ash cloud produced covered much of Northern Europe for several weeks causing extensive disruption to air travel. The UK and European atmospheric communities had many instruments - both airborne and ground-based, remote sensing and in-situ - taking measurements of the ash cloud throughout this period. This dataset contains Leosphere and Halo Doppler Lidar images from the Chilbolton Observatory, Hampshire.

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)
