Information om forskning och undervisning


My research focuses on cloud and precipitation physics. We use remote sensing observations to capture microphysical processes that govern cloud and precipitation properties.

Our group carries out observations in Helsinki, by using the Kumpula radar, and in Hyytiälä. At the SMEAR-II station in Hyytiälä, we operate ACTRIS cloud remote sensing facility. These observations are supplemented by a comprehensive suite of surface-based precipitation sensors, which allows us to connect cloud processes and surface precipitation properties. In addition to cloud studies, this research facility is used for validation of satellite observations, i.e. NASA GPM and upcoming ESA EarthCARE.
