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. vessel:polarstern:weather (22) |

The weatherstation consists of different sensors (see: subdevices) and a data acquisition unit. The data acquisition unit developed by AWI in colaboration with [FIELAX|http://www.fielax.de] provides local data storage and data transfer to the DShip system. |
|
|
|
Time synchronising is regulated via ntp between the acquisition computer xdas1 and the central ntp-server on board. Geographical ship's position via DShip. |
