The camera was facing South in a trailer next to the UFAM 1290MHz wind profiler. The camera was a Logitech QuickCam Pro 4000 webcam. Its data availability was patchy at first, but it provided continuous imagery during July and August at 30 s sampling.

The data were collected by radiosonde at Reading by Convective Storm Initiation Project (CSIP) participants at the University of Reading between the 16th of June 2005 and the 25th of August 2005. Data include measurements of air temperature, relative humidity, wind speed and direction, and air pressure.

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. The project was centred on the 3 GHz (CAMRa) and 1275 clear-air (ACROBAT) radars at Chilbolton and used a number of the new UK Universities' Facility for Atmospheric Measurement (UFAM) mobile instruments. This dataset includes measurements of wind speeds and wind directions and aerosol concentrations.

The University of Salford automatic weather station data describe observations made every 5 seconds with the data stored every one minute and 10 minutes at Faccombe wind turbine field site, Hampshire, form the 3rd of June 2005 until the 26th of August 2005.. The dataset contains measurements of the following parameters: Average air temperature Average dew point (measured from 11:54 BST 22nd June 2005) Average relative humidity Average net radiation Average wind speed Maximum wind speed Time of maximum wind speed Total rainfall Average pressure Average wind direction Minimum wind direction Maximum wind direction Average battery Two jpeg images files have been produced from the AWS data for each day from 3rd June 2005 (start of CSIP field project) until 26th August 2005 (end of CSIP field project). There are two image files, the first image file listed below contains plots of the windspeed, pressure and rainfall with time for a particular day. The second image file contains air temperature, relative humidity and net radiation plots with time for a particular day. The weather station consists of a Campbell Scientific 2 m tripod with a CR10X datalogger. Weather station sensors include a MP100A temperature and relative humidity probe, a A100L2 low power anemometer, a W200P potentiometer wind vane, a NR-Lite Net Radiometer, a RPT410F barometric pressure sensor and a ARG100 Tipping bucket rain gauge.

The University of Salford radiometer data describe observations taken by microwave radiometer that was situated at the Faccombe wind turbine field site, Hampshire and collected data from 24th June 2005 until 26th August 2005. T The dataset contains measurements of the following parameters: Liquid Water Path (LWP) time series – 1 second measurement time Integrated Water Vapour (IWV) time series – 60 seconds measurement time Humidity Profile (full troposphere) (HPC) – 60 seconds measurement time Temperature Profile (full troposphere) (TPC) – 60 seconds measurement time Temperature Profile (boundary layer) (TPB) – 200 s measurement time A boundary layer temperature profile was taken every 10 minutes which took 200 seconds to complete. When not operating a boundary layer scan, the radiometer operated in zenith mode and measurements of LWP, IWV and the tropospheric temperature and humidity profiles were made. Calibrations were performed every 20 minutes, 6 hours and 24 hours. The boundary layer temperature measurements (0 – 2000 m) have a vertical resolution of 50 m. The tropospheric temperature measurements (0 – 10000 m) have a vertical resolution of 200 m. The tropospheric humidity profiles (0 – 6000 m) have a vertical resolution of 200 m (0 – 2000 m) and 400 m (2000 – 6000 m). Two jpeg images files have been produced from the radiometer data for each day from 24th June 2005 until 26th August 2005. The first image file contains separate profiles of temperature up to 2 km and 10 km and profiles of absolute and relative humidity up to 10 km. The second image file contains a time series of the integrated water vapour and liquid water path.
