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). Helium is calculated to supply one 600 gramm balloon per day. If additional radio sonde ascents are planned, the user has to organize the additional sondes, balloons and helium. 

Summary

The radiosonde sounding system gathers meteorological data (pressure, temperature, humidity, wind, position) from a mandatory radiosonde and data from additional sensors like ozonesonde (ozone), cryogenic frostpoint hygrometer (CFH; stratospheric water vapour) and COBALD (aerosol) as well as from ground based sensors (standard humidity chamber, and others)

No parameters available.

Central geographical ship's position and time standard

Time synchronising is regulated via onboard NTP server.
Geographical ship's position via unit's GPS receiver.

Rawdata storage on board

Mass data: The data acquisition software creates rawdata on the local drive of the sounding computer and in the mass storage.

Data archiving on land

After the cruise, the operator transfers the measurement data along with required meta data to AWI after consultaion with the data scientist and AWI Logistics. Then, the data (including meta data) can be extracted from https://www.pangaea.de/ (for authorized users only).
