The San Joaquin Valley (SJV) campaign is part of an effort to integrate observations of vegetation water content, soil moisture, and evapotranspiration into agricultural water management and better understand water balance and fluxes. Observations of vegetation, in particular vegetation water content, will be estimated using AVIRIS and supported by concurrent ground measurements. Evapotranspiration will be determined using MASTER observations of land surface temperature and flux tower measurements. Both instruments will be flown in the morning and afternoon to check for changes in evapotranspiration and vegetation water content throughout the day. Soil moisture will be retrieved from the UAVSAR and supported by concurrent ground measurements. The measurements made by the UAVSAR will also address several algorithm development issues for the NASA Soil Moisture Active Passive (SMAP) mission ( http://smap.jpl.nasa.gov).
