Passive microwave observations from various spaceborne sensors have been linked to the soil moisture of the Earth’s surface layer. A new generation of passive microwave sensors are dedicated to retrieving this variable and make observations in the single theoretically optimal L-band frequency (1–2 GHz). Previous generations of passive microwave sensors made observations in a range of higher fre...

Abstract. Climate change increases the occurrence and severity of droughts due to increasing temperatures, altered circulation patterns, reduced snow occurrence. While Europe has suffered from drought events in last decade unlike ever seen since beginning weather recordings, harmonized long-term datasets across continent are needed monitor support predictions. Here we present soil moisture data...
