It is mounted in inverse position about 0.9 m above ground using Boltek 3 feet tripod inverting mounting kit.  The EFM-100 is located on the grass away from elevated objects. \r\nCalibration was done using a reference EFM-100 located on the ground surface at several places around the installed EFM-100 to find a correction factor, which is applied on raw data.\r\nAnalog output of EFM-100 is sampled at 25 Hz by dedicated datalogger with GPS time stamping. Data are stored in specific binary format.\r\n","keywords":"","identifier_set":[],"instrumentType":"","subInstrument":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/102611/?format=json"]}
