Antarctic Precipitation : REmote Sensing from Surface and Space

The antarctic region is still Terra Incognita in the global precipitation databases. The 1st climatology which does not heavily relies on models was recently published (2014). It is obtained from satellite-born radar data. The project is to deploy 1 or 2 summer campaigns at Dumont d’Urville to study the variability and microphysics of Antarctic precipitation in the coastal regions, as well as to calibrate and validate those data. The Ecole Polytechnique Fédérale de Lausanne meteorological radars, hydrometeor detecting lidars (Swiss and Italian), and the 70-m vertical profiling system from the CALVA program will be used during the field campaigns. It will be particularly interesting to operate the surface radars looking upward while the space radar overpasses, in order to directly cross the output from both sides of the atmosphere.
