Accuracy assessment of MODIS Airborne Simulator (MAS): 1996 to 1998

摘要

Abstract: In an effort to provide accuracy assessment of the visible and shortwave IR (SWIR) channels of MODIS Airborne Sensor (MAS), the result of three in-flight calibration/validation experiments from 1996-1998 are presented. Both MAS and Airborne Visible IR Imaging Spectrometer (AVIRIS) were flown together on NASA's ER-2 over two bright targets. Additionally MAS acquired another bright target, Ivanpah Playa, in 1998. AVIRIS data were spectrally and spatially convolved to MAS specifications for cross comparisons. Predicted at sensor radiances using MODTRAN 3.5 constrained with in situ data are then compared to MAS and convolved AVIRIS radiances for absolute radiometric calibration. !2
