Giulia Panegrossi

Research Activity

My research interests include remote sensing of clouds and precipitation; passive microwave precipitation retrieval algorithms; radiative transfer through precipitating clouds; microphysics characterisation of precipitating clouds using models and observations; development of microphysics schemes; cloud electrification; nowcasting techniques; analysis of heavy precipitation events through the use of NWP models (UW-NMS, MM5, WRF-ARW) and comparison with remote, ground-based and in-situ measurements. My current scientific activity is mainly related to the development of passive microwave (PMW) precipitation retrieval algorithms for the cross-track and conically scanning radiometers in the Global Precipitation Measurement (GPM) mission constellation of satellites, PMW snowfall retrieval with focus on high-latitudes, global precipitation climatology, extreme events in the Mediterranean area, water cycle, hydrological applications. This activity is carried out within different international and national projects.
