This ongoing research project is a collaborative effort between scientists at the University of Maryland and NASA’s Goddard Space Flight Center. The research is focused on developing new approaches to integrate active and passive microwave remote sensing data to map hydrologic conditions (soil moisture and levels of water inundation) in boreal regions.  This study will provide insights on how to exploit data that will be collected by NASA’s forthcoming Soil Moisture Active Passive (SMAP) satellite system.
