Surface precipitation measurements from the precipitation sensor on the Vaisala WXT510 instrument deployed at the Natural Environment Research Council's (NERC) Mesosphere-Stratosphere-Troposphere (MST) Radar Facility, Capel Dewi, near Aberystwyth in West Wales.
These data are available to any registered CEDA user under the UK Open Government Licence.
Surface pressure, temperature and humidity data (PTU) from this instrument are also available as a separate dataset within the MST Radar Facility dataset collection.
The WXT-510 instrument at the site began operational recording in December 2007 and ceased in January 2015, subsequently being replaced by a Vaisala WXT-520 instrument. The WXT520 data are also available from CEDA as part of the MST Radar Facility's dataset collection.
Independent surface meteorological data are also collected from a suite of instruments by a Campbell Scientific CR10 Climate Data Logger. These data are available as a separate dataset within the MST Radar Facility dataset collection.

Use of these data is covered by the following licence: http://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/. When using these data you must cite them correctly using the citation given on the CEDA Data Catalogue record.
Data were acquired by the MST radar facility and sent to the British Atmospheric Data Centre (BADC) within an hour of acquisition. Data were then immediately ingested into the BADC archives.
The MST radar data quality is described by D. A. Hooper, J. Nash, T. Oakley, and M. Turp. Validation of a new signal processing scheme for the MST radar at Aberystwyth. Ann. Geophys., 26(11):3253-3268, 2008. (available from here http://www.ann-geophys.net/26/3253/2008/angeo-26-3253-2008.html)
Data are in Climate and Forecast conventions (CF) compliant netCDF files.
