The weatherstation consists of different sensors (see: Subdevices) and a data acquisition unit. The data acquisition unit developed by [FIELAX|http://www.fielax.de] provides local data storage and data transfer to the DShip system. In addition,
it facilitates the receipt of weather information and satellite images. The German Weather Service (DWD) provides the required forecast producst via e-mail.

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. |
