HSL's Amy McNally (above, foreground), Grey Nearing, and Kiersten Newtoff have joined a SMAP calibration and validation field campaign in the Yanco region of Australia (380 miles west of Sydney) led by International SMAP science team member Jeff Walker (Monash University, Melbourne, Australia). It includes ground soil moisture and vegetation sampling and aircraft active and passive L-band sensor measurements coincident with observatory passes over the region. The campaign runs from May 2 through May 22 and includes scientists from Australia, Netherlands, Germany, France and the United States, including NASA and U.S. Department of Agriculture (USDA).
