Abstract

Surface wind measurements are available from the Vaisala WXT510 surface meteorology instrument deployed at the Natural Environment Research Council's (NERC) Mesosphere-Stratosphere-Troposphere (MST) Radar Facility, Capel Dewi, near Aberystwyth in West Wales from 2007 to 2015. Wind speed and direction are measured by a WINDCAP (R) sensor which consists of an array of three equally-spaced ultrasonic transducers. These transducers are situated approximately 11 cm apart in a horizontal plane, leading to minimum, mean, and maximum values of speed and direction to be recorded. Data are available in netCDF formatted data files to all CEDA registered users under the UK Open Government licence.

This instrument has since been replaced by a Vaisala WXT520 surface meteorology instrument at the site.

Note - the wind data from this instrument are known to be highly constrained by the valley topography in which the instrument is sited. As such it should not be used as a representation of the broad scale wind field, but may be of interest to those wishing to study valley flows.

Access rules:
Access to these data is available to any registered CEDA user. Please Login or Register for an account to gain access.
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 lineage:

These data were acquired by the MST radar facility and sent to the BADC (subsequently CEDA) within an hour of acquisition. Data were then immediately ingested into the BADC archives.

Data Quality:
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)
