Atmosphere

The challenge is to obtain regular and reliable data from unmanned platforms and stations

Atmospheric data are well organized under the auspices of the WMO’s global World Weather Watch and are available through national meteorological services. The challenge is to obtain regular and reliable data from unmanned platforms/stations. In the Arctic instruments ice-up within a matter of hours and in many cases it is impossible to determine a faulty sensor from a functional one by analysing the observations. Therefore, the operational network of atmospheric in situ observations to date is very sparse, over Arctic land and non-existing over the Arctic Ocean. It is therefore a challenge to develop autonomous instruments or measurement strategies that work in the harsh Arctic environment with a minimum of power requirements. Semi-autonomous instruments deployed on ships of opportunity are promising for obtaining more data from the Arctic.
