  • 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 University of Salford sonic anemometer 2 data describe observations taken by a 7 meter sonic anemometer at Faccombe wind turbine field site, Hampshire. The dataset contains measurements of wind speed collected from 21st July 2005 until 26th August 2005. The dataset contains measurements of the following parameters: Latitude; the latitude of the sonic anemometer (degrees north) Longitude; the longitude of the sonic anemometer (degrees east) Altitude; the altitude of the sonic anemometer base above mean sea level (m) Height ; the height of the sonic anemometer head above ground level (m) Measurement rate; the measurement rate of the sonic anemometer, set at either 1 or 10 Hz Sonic Orientation; the orientation of the sonic coordinate system, clockwise, to convert from sonic to meteorological coordinates (degrees) Time; time in seconds from midnight UTC for each measurement (s) X wind; the wind speed along the orthogonal x direction (m s-1) Y wind; the wind speed along the orthogonal y direction (m s-1) Upperward air velocity; the wind speed along the orthogonal z direction (m s-1) Sonic virtual temperature; the sonic virtual temperature, average between the three non orthogonal sonic axes, related to the speed of sound (K) The sonic anemometer is a Campbell Scientific CSAT3 using a CR5000 datalogger. The 7 m sonic was mounted on a Clark QTM mast.

  • The dataset contains images of the UFAM (Universites' Facility for Atmospheric Measurements) 1290MHz wind-profiler site at Linkenholt, Hampshire from the 11th June 2005 to the 31st of August 2005. NOTE: From 11/06/2005 to 16/06/2005 the timestamp in the picture is GMT from 18/07/2005 to 31/08/2005 the timestamp is BST. 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 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 photograph data are digital photographs taken approximately every 30 minutes at the Faccombe wind turbine site, Hampshire. The dataset contains photographs taken on four days between the 11th of August 2005 and 25th of August 2005. The latitude and longitude of the field site is N 51°19.51’ and W 1°26.46’ respectively. Photographs were taken approximately every 30 minutes and the pictures are orientated to a bearing of 310°.

  • 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 Leeds Sodar 1 dataset contains measurements of the scattering of sound waves by atmospheric turbulence at Chilbolton Observatory, Hampshire over the periods from the 6th of July to the 27th of July 2004 and from the 10th of June 2005 to the 19th of August 2005. The dataset contains measurements of wind speed at various heights above the ground, and the thermodynamic structure of the lower layer of the atmosphere.

  • The University of Aberystwyth mobile ozone lidar data contain measurements of ozone mixing ratios and aerosol information. The data were collected at Chilbolton observatory, Hampshire on the 7th and the 8th of June 2005. The data collected on the 7th of June 2005 are of ozone mixing ratios only. The data collected on the 8th of June 2005 are of ozone mixing ratios, aerosol backscatter, and boundary layer height information.

  • The Institute of Meteorology and Climate Research (IMK) Lidar Data are images displaying the polar wind velocity and the polar aerosol concentration. For elevation scans there are figures at azimuth 0, 60 and 120 degrees, for the azimuth scan there are figures at elevations 7, 12 and 17 degrees available. Angles are indicated in the line above the colourscale. Vertical scans have been made at elevation 90 degree. The upper figures are showing polar (radial) velocity, the lower ones aerosol backscatter at the three different angles which are indecated in each figure above the colour scale. The diagrams are showing unaveraged data. They vizualize a snapshot of approx. 10 minutes measurements starting at the time stated in the filename. Data were recorded from the 19th of June 2005 to the 29th of August 2005.
