AIRSAR was provided generously by Bruce Chapman of the National Aeronautics and Space Administration (NASA), made possible by grants from the National Science Foundation (BCS # 0406472; Sharer, PI) and the National Geographic Society (# 7575-04; Quilter, PI).
To identify groundwater seepage areas, the research team looks at soil `dielectric property' information derived from the AIRSAR data.
The information is collected as the DC-8 aircraft flies over target terrain, while the AIRSAR instrument transmits continuous pulses of microwave energy onto the earth's surface.
An integrated perspective, made possible by the comprehensive AIRSAR coverage, is required to understand the nature and overall operation of the network.
