Attention:
The system is operated by staff from the German weather service (DWD). Scientific co-use is possible according to prior agreement with AWI Logistics and Principal Investigator of the Polarstern Meteorological Observatory (Holger Schmithüsen).
Summary
The Digicora Sounding System receives measurements (temperature, humidity, position) from a radiosonde and processes them for further use.
