Automatic Weather Station (BAS) The automatic weather station is designed to be installed on

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. 2 m height. The platform reports GPS position and atmospheric data via iridium.
