It is mounted on a 0.6 m metal pole.\r\nThe provided data was calibrated using long-term observation of water dropper data (Nagamachi et al, Geosci. Data J., 2021). The resolution of the sensitive data provided through GLOCAEM is 1.9 V/m and the measurement range is from -3.8 kV/m to +3.8 kV/m. GPS-synchronized data with higher resolution (0.19 V/m) and with high sampling (10 Hz), all-sky camera images (10 min. sampling), animal camera images (motion detection) and are also available through on-demand request.\r\n\r\nThe instrument is located at 27 m a.s.l.\r\nMeasurement frequency is 1Hz\r\n\r\nThis is used in the  Glocaem potential gradient network","keywords":"glocaem","identifier_set":[],"instrumentType":"instrument","subInstrument":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/193785/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/193787/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/193784/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/193786/?format=json"]}
