Polar Meteorology / Ice Core Interpretation

Research Interest

The stable isotope ratio of polar ice is one of the crucial proxies to derive paleotemperatures. For a correct interpretation of ice core data, however, we need to fully understand the precipitation mechanisms that lead to the formation of the ice. This includes moisture sources and transport as well as meteorological conditions at the time and location of snow deposition. To investigate this we use recent stable isotope and meteorological station data combined with high-resolution atmospheric modeling. Our focus is on process studies in Antarctica.
