Surface meteorological data are measured by a number of instruments deployed at the Natural Environment Research Council's (NERC) Mesosphere-Stratosphere-Troposphere (MST) Radar Facility, Capel Dewi, near Aberystwyth in West Wales. This dataset consists of data collected by the following suite instruments connected to a Campbell Scientific CR10 Climate Data Logger: Campbell Scientific 107 thermistor temperature probe mounted inside an URS1 unaspirated radiation shield. Accuracy: +/- 0.4 degrees C. Vaisala PTB101B barometric pressure sensor. Accuracy: +/- 2.0 hPa. Vaisala HMP45C temperature and relative humidity probe (from which only the humidity measurements are used) mounted inside an URS1 un-aspirated radiation shield. Accuracy: +/- 0.3%. Environmental Measurements ARG100 tipping bucket raingauge. Kipp and Zonen CM3 thermopile pyranometer (WMO second class). Accuracy: +/- 0.5%. The raingauge is located on the ground. All other sensors are mounted on a post approximately 1 m above the ground.
The data logger initially samples the atmospheric temperature, pressure and humidity sensors at 5 s intervals. Mean values are calculated over each 60 s and the outputs from the logger represent minima, means and maxima of these 60 s means over each 10 minute sample period. The data logger is connected to a tipping bucket raingauge (sampled every 1 s, and recording tips for each 0.20 mm accumulation of rain); pyranometer (sampled every every 5 s, recording the down-welling radiation within a hemispheric field of view with a flat response in the spectral range 305 - 2800 nm);
The data are available in NASA-Ames formatted files.
Independent surface meteorological data are also available from the Vaisala WXT510 instrument also located at the site and are available in the wxt510-precipitation and PTU datasets.

Data are acquired by the MST radar facility and sent to the BADC within an hour of acquisition. Data are then immediately ingested into the BADC archives.
