MODIS Airborne Simulator
The MODIS Airborne Simulator (MAS), which flies onboard the NASA ER-2 high altitude aircraft, currently supports product development and validation efforts for two satellite-based instruments, the MODerate-resolution Imaging Spectroradiometer (MODIS) and the Atmospheric InfraRed Sounder. Prior to the launch of MODIS in 1999, MAS was used in several field campaigns as a test bed for developing and testing MODIS cloud products. Scientists use MAS data to assess the accuracy of MODIS measurements, how well MODIS can detect clouds, and to determine cloud height and the contents of cloud particles. MAS data sets are also used with other instruments to support research on cloud detection and characterization, land surface emission, and water turbidity. MAS continues to support validation efforts for future satellite-based instruments.
