A sonic anemometer can provide rapidly updated measurements of the wind components, faster than a conventional cup and vane anemometer. This makes it particularly suitable for eddy covariance measurements and studies of turbulence. It operates continuously.\r\n\r\nThe Metek USA-1 sonic anemometer measures the 3 orthogonal components of the wind velocity by measuring the changes in the time of flight of sonic pulses between 3 transmitter/receiver pairs as a result of the air velocity.\r\n\r\nData are measured at 20Hz, with output recording the zonal, meridional and vertical wind speeds.","keywords":"sonic anemometer, Chilbolton","identifier_set":["https://catalogue.ceda.ac.uk/api/v2/identifiers/8571/?format=json","https://catalogue.ceda.ac.uk/api/v2/identifiers/13303/?format=json"],"instrumentType":"anemometer","subInstrument":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/51415/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/51416/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/51417/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/51418/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/210895/?format=json"]}
