The observatory is always manned with a weather radio technician and a meteorologist during scientific cruises. The facilities of the meteorological observatory can be co-used by scientists for special measurements.


The weather station at Polarstern consists of several devices which measure standard parameters such as temperature, wind, humidity, barometric pressure, radiation and precipitation. Satellite images are received with a dedicated antenna which, together with the data, are used for forecast purposes. The station is operated by a weather technician-observer from the German Weather Service (DWD) who is responsible for the routine 3-hourly synoptic observations and the daily upper air soundings.

The weatherstation consists of different sensors (see: subdevices) and a data acquisition unit. The data acquisition unit developed by AWI in colaboration with FIELAX provides local data storage and data transfer to the DShip system.
