Abstract/Summary

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, therefore collecting data would allow testing numerical models on mass flux over that region. A present weather station (PWS) Biral VPF730 has been set up at the coast in Cap Prud'homme station, 5km away from Dumont D’Urville (DDU), firstly to quantify precipitation. As we could expect determination of blowing snow fluxes from the PWS data, we first choose to test such a device on our experimental site, the Lac Blanc Pass. An empirical calibration was done with a SPC (Snow Particle Counter). Even if the physics of phenomenon was not well capture, the fluxes outputs are better than those from the FlowCapt. The first data from Antarctica were re-analyzed. The new calibration seems to be accurate for estimating the high blowing snow flux with an interrogation for the precipitation effects.
