Short summary

To derive paleotemperatures from ice cores we must know all processes involved in ice formation. At the Antarctic base Dome C, a unique precipitation data set plus stable water isotope data enabled us to study atmospheric processes influencing isotope ratios of precipitation in detail. Meteorological data from both automatic weather station and an atmospheric model were used to investigate how different atmospheric flow patterns determine the precipitation parameters used in paleoclimatology.
