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. \r\n\r\nThe 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); \r\n\r\nThe data are available in NASA-Ames formatted files.\r\n\r\nIndependent 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.","keywords":"MST, meteorology, surface, 2m, pressure, temperature, humidity","publicationState":"published","dataPublishedTime":"2007-03-15T23:52:33","doiPublishedTime":null,"updateFrequency":"daily","status":"ongoing","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/6123/?format=json","dataPath":"/badc/mst/data/surface-met","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":109578853,"numberOfFiles":8417,"fileFormat":"Data are available in NASA-Ames formatted files."},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/1790/?format=json","geographicExtent":"https://catalogue.ceda.ac.uk/api/v2/bboxes/515/?format=json","nonGeographicFlag":false,"phenomena":["https://catalogue.ceda.ac.uk/api/v2/phenomona/8242/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/8243/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/8244/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/8245/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/8246/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/8247/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/8248/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/8249/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/8250/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/8251/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/22457/?format=json"],"dataLineage":"Data are acquired by the MST radar facility and sent to the BADC within an hour of acquisition.
