Arbeitsgruppe Fernerkundung

The working group focusses on the full understanding and exploitation of polarimetric weather radar measurements for quantitative precipitation estimation (QPE), nowcasting (QPN), detailled evaluation of numerical models in radar-observation and retrieval space, parameterization improvement/development for a better representation of cloud and precipitation processes in numerical weather prediction models, and also for (polarimeric) data assimilation. Strong collaborations with the German Weather Service enable the implementation of developments in operational applications. Even though a focus is on ground-based weather radars, synergistic measurements are in multifold use, e.g. commercial microwave links to improve radar-based QPE, statellite overpasses for radar calibration, satellite-based retrievals to consider convective initiation and enhance the lead-time of radar-based nowcasting, multi-frequency cloud radars to complement process understanding, and airborne in-situ measurements to evaluate polarimetric retrievals.
