MODIS/ASTER AIRBORNE SIMULATOR
The MODIS/ASTER Airborne Simulator (MASTER) is a modified Daedalus Wildfire scanning spectrometer which flies on a variety of multiple altitude research aircraft and provides spectral information similar to that which is provided by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and the Moderate Resolution Imaging Spectroradiometer (MODIS) and, which is aboard two of NASA Earth Observing System Satellites, TERRA & AQUA.
The principal scientific investigator for MASTER is Dr. Simon Hook, an Earth Surface Scientist at the NASA Jet Propulsion Laboratory.
