Abstract :
Three new L band passive satellite missions to measure sea surface salinity and soil moisture are reviewed. The first is the ESA Soil Moisture Ocean Salinity (SMOS) satellite. It features the first spaceborne synthetic aperture antenna with enhanced resolution and multiple incident angle looks. The second is the NASA Aquarius mission to sense sea surface salinity with a 0.2 psu accuracy and an on-board radar to correct for surface roughnesss. The last is NASA´s Soil Moisture Active Passive (SMAP) mission to measure soil moisture with a 6m mesh antenna for increased resolution and a radar to enhance its performance.
