PD Dr. S. Trömel is heading the working group on radar polarimetry and its applications at the Institute of Geosciences in Bonn. She brings together observationalists, numerical modelers, and hydrologists to foster a better model representation and prediction of cloud and precipitation processes. She is heading the FOR-2589 on "Near-Realtime Quantitative Precipitation Estimation and Prediction" (RealPEP) and the SPP-2115 "Fusion of Radar Polarimetry and Numerical Atmospheric Modelling Towards an Improved Understanding of Cloud and Precipitation Processes" (PROM). She is Deputy Director of ABC/J Geoverbund and, together with Prof. U. Löhnert, leading the competence center CPEX-Lab (Clouds and Precipitation Exploration Laboratory) of the Geoverbund ABC/J.
