Our Department is one of the partners in the ESA project Irrigation+. In the context of this project, the potential for inferring rainfall measurements from satellite data at higher resolution than the current usual one was analysed. For the study area of the Po River basin our colleague Raphael Quast prepared the Sentinel-1 soil moisture data set to which our colleagues at the Research institute for geo-hydrological protection (IRPI) in Perugia, Italy, applied the SM2RAIN (Soil Moisture to Rain) algorithm.
