Present weather sensor tests for measuring drifting snow
In Antarctica, blowing snow accounts for a major component of the surface mass balance near the coast. Measurements of precipitation and blowing snow are scarce, and therefore collecting data would allow testing numerical models on mass flux over this region. A present weather station (PWS), Biral V...
