TI  - Etude des précipitations à Dome C sur le plateau antarctique
N2  - Although antarcic precipitation has been studied for about half a century, the rate and occurrence of precipitation on the Antarctic Plateau are still unknown. During the summer campaign 2015-2016, a TPS-3100 (or Hotplate) precipitation gauge was set-up at Dome C to test the ability of such an instrument to measure precipitation in the climate conditions of the Antarctic Plateau. The TPS-3100 consists of two identical heated and thermally insulated aluminium disc plates. One of the plates faces up and measures the rate of precipitation, the other faces down and serves as a reference. The two plates are heated independently and maintained at a constant temperature of 75 ° C. An analysis of the data collected by the TPS-3100 and a characterization of the precipitation events at Dome C over the year 2016 were carried out in this study. Hotplate’s measurements have been found to generally disagree with ECMWF interim analyses and reanalyses and LMDZ simulations, not only in terms of quantity but also occurrence. However, it remains difficult to disentangle between errors in the measurements and those in the other datasets since there is no benchmark data set for precipitation rates at Dome C.
