NASA studies vegetation canopy water content, soil moisture

NASA's MASTER and AVIRIS spectrometers mounted in the ER-2, a civilian version of the Air Force's U-2, gathered data from 65,000 feet altitude at about 11 a.m. and again about 3 p.m. during flights in May and November 2011. The ER-2 can acquire MASTER and AVIRIS data simultaneously, with both instruments tracking estimates of vegetation water content. In addition, MASTER monitors evaporation and transpiration.The G-III carries the Unmanned Aerial Vehicle Synthetic Aperture Radar designed and operated by NASA's Jet Propulsion Laboratory in Pasadena, Calif. Located in a specialized pod attached to the belly of the aircraft, the sensor acquires repeat-path data from an altitude of 41,000 feet. During four flights over the target area at solar noon, or roughly 1 p.m., in June 2010 and May, June and November 2011, the UAVSAR collected data to determine soil moisture changes. Two of the G-III's missions took place on days the ER-2 flew.
