  • 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.
