  • 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.

  • The Rutherford Appleton Laboratory (RAL) Cloud Radar was deployed at the Natural Environment Research Council's (NERC) Mesosphere-Stratosphere-Troposphere (MST) Radar Facility, Capel Dewi, near Aberystwyth in West Wales from April 2005 to June 2006. These data are restricted to registered users for these data only.

  • Data from the Met Office's 915 MHz LAP3000 UHF (Ultra High Frequency) boundary layer wind profiler deployed at the Natural Environment Research Council (NERC) Mesosphere-Stratosphere-Troposphere (MST) Radar Facility, Capel Dewi, near Aberystwyth in West Wales. The instrument was deployed from February 1995 to March 2002. These data are made available under the NERC-Met Office agreement.

  • Integrated water vapour (IWV) data from the Met Office's GPS instrument located at the Natural Environment Research Council (NERC) Mesosphere-Stratosphere-Troposphere (MST) Radar Facility, Capel Dewi, near Aberystwyth in West Wales. These data are restricted (please use the apply for access link) and made available under the NERC-Met Office agreement.

  • Images from the sky camera mounted at the Natural Environment Research Council's (NERC) Mesosphere-Stratosphere-Troposphere (MST) Radar Facility, Capel Dewi, near Aberystwyth in West Wales. Images are in jpeg format.

  • Data from the instruments at the Natural Environment Research Council (NERC) Mesosphere-Stratosphere-Troposphere (MST) Radar Facility near Aberystwyth in West Wales. The principal measurements made by the MST radar are of the three dimensional wind vector over the altitude range 2 - 20 km. Surface meteorological measurements from the radar site, ceilometer data, sky camera images and wind speed and direction recorded from a 10m tower located 6km away are also available. Other instruments at the facility have included one of the Met Office's boundary layer wind profilers and NCAS's boundary layer wind profiler.

  • Radiosonde data from balloon flights from the Aberporth airfield made available for comparison with data from Natural Environment Research Council's (NERC) Mesosphere-Stratosphere-Troposphere (MST) Radar Facility, Capel Dewi, near Aberystwyth in West Wales. Data are ASCII formatted, containing height in km, wind speed and direction, temperature and dew-point temperature. A more complete set of high resolution radiosonde data are available in the Met Office High Resolution Radiosonde dataset.

  • Surface pressure, temperature and humidity data (PTU) were collected by a Vaisala WXT510 instrument located at the Natural Environment Research Council's (NERC) Mesosphere-Stratosphere-Troposphere (MST) Radar Facility, Capel Dewi, near Aberystwyth in West Wales. Rainfall rate data 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.

  • 10m surface wind speed and direction data are available from instruments mounted on a 10m tower at the Frongoch site, 6km away from the main Natural Environment Research Council (NERC) Mesosphere-Stratosphere-Troposphere (MST) Radar Facility's site in Wales. Wind direction is obtained from a Vector Instruments W200P wind vane and wind speeds from a Vector Instruments A100R anemometer.

  • 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.
