The Natural Environment Research Council (NERC) Mesosphere-Stratosphere-Troposphere (MST) Radar Facility, Capel Dewi, UK, is managed by RAL Space in collaboration with University of Manchester and the University of Aberystwyth. The facility host a range of atmospheric instruments including the UK's MST radar, surface meteorological instrumentation and lidars. The facility is also able to host guest instruments. The facility was officially opened on 12th November 1990. The facility also operates instrumentation at the nearby Frongoch site.

More Information (under review)
The Natural Environment Research Council (NERC) Mesosphere-Stratosphere-Troposphere (MST) Radar at Aberystwyth is:
- the UK's most powerful and versatile wind-profiling instrument
- provides measurements of the vertical as well as the horizontal components of the wind
- is operated predominantly in the ST mode, covering the approximate altitude range 2 - 20 km at 300 m resolution
- is operated on a continuous basis, with a cycle time of a few minutes
- can, under suitable circumstances, provide information about atmospheric stability, turbulence, humidity fields, and precipitation
- has been making mesospheric observations, i.e. covering the altitude range 56 - 94 km, continually since April 2005
The data products are freely available through the British Atmospheric Data Centre.
The radar site is located at Capel Dewi (52.42°N, 4.01°W), near Aberystwyth in west Wales (UK).
The Facility additionally operates and hosts a number of instruments whose observations complement those made by the MST radar. Other data products include surface measurements of meteorological parameters (i.e. wind-speed and direction, temperature, pressure, humidity, solar radiation and rain rate), cloud base altitudes and sky images.
