Automatic Weather Station (BAS) The automatic weather station is designed to be installed on an ice floe, measuring air temperature, barometric pressure, relative humidity, short and long wave radiation as well as wind speed and direction at approx. 2m height. The platform reports GPS position and atmospheric data via iridium. Buoy description Manufacturer: British Antarctic Survey Manufacturer‘s name: Data provider AST Weight approx. 100 kg Deployment type Installation on sea ice through 25 cm hole Technical Details Measured parameters Sensor Air temp.
