The Met Office deployed a Vaisala Radian LAP3000 915 MHz wind profiler at the Natural Environment Research Council's (NERC) Mesophere-Stratosphere-Troposphere (MST) Radar Facility site at Capel Dewi, near Absersywyth, Wales, from November 1999 to March 2002. This deployment was to co-locate this UHF boundary layer wind profiler with the NERC MST VHF wind profiling radar - giving a combined coverage between the two instruments from around 300m to 20 km. At the time the Met Office's 915 Mhz wind profiler was an integral part of the Met Office's UK "Operational Upper Air Network", providing high resolution wind information from just above the surface (around 300m) up to a maximum of 8 km, depending on the atmospheric conditions. The Capel Dewi site is located at 52.42 N, 4.01 W and a height of 92 m above mean sea-level. The site has a WMO id of 03501. The instrument's hight resolution is 60/200 m depending on the operational mode. It has a beam angle of 15.0 degrees and is operated with an averaging period of 30 minutes. This instrument was subsequently deployed at South Uist and then at its present location on the Isle of Man.

This dataset contains vertical wind profiles from the Vaisala Radian LAP3000 915MHz wind profiler located at Capel Dewi.
