Jan Lieser
Jan graduated in meteorology at the Free University of Berlin in 1996. His Diploma thesis was on the analysis of sequential satellite imagery from Advanced Very High Resolution Radiometer (AVHRR) to derive kinematic information from displacement vector fields. In 1998 Jan was the wintering scientist at the German Neumayer research station in Antarctica (70°39' S, 08°15' W), which is run by the Alfred Wegener Institute for Polar and Marine Research (AWI). Jan was responsible for the meteorology and air chemistry observatories.
Following his winter in Antarctica Jan studied for his PhD at the AWI on the development of a numerical sea ice forecast model for the Arctic Ocean. He graduated at Bremen University in 2004. In 2001, 2003, and 2004 he participated in three cruises of the German icebreaker RV Polarstern to the central Arctic Ocean. His research focus was on sea ice physics with a special interest in sea ice thickness estimates with a new helicopter borne electromagnetic induction device (EM-Bird). Jan also worked as a Post-Doc at the AWI on model analysis in support of sea ice field camps and expeditions and at the Commission for Glaciology at the Bavarian Academy of Sciences and Humanities investigating the internal circulation of subglacial Lake Vostok, Antarctica.
Jan's current research interest include airborne laser altimetry for sea ice thickness measurements to validate space-borne remote sensing products (for example ICESat, and upcoming CryoSat) and short-term forecasting of sea ice conditions in the Antarctic in support of ship operations.
