NASA MAS_eMAS Project

The Enhanced Moderate Resolution Imaging Spectroradiometer (MODIS) Airborne Simulator (eMAS)instrument is maintained and operated by the Airborne Sensor Facility at NASA Ames Research Center in Mountain View, California, under the oversight of the EOS Project Science Office at NASA Goddard. Prior to 1995, the MAS was deployed on the NASA's ER-2 and C-130 aircraft platforms using a 12-channel, 8-bit data system that somewhat constrained the full benefit of having a 50-channel scanning spectrometer. Beginning in January 1995, a 50-channel, 16-bit digitizer was used on the ER-2 platform, whic...增强型中分辨率成像光谱仪（MODIS）机载模拟器（eMAS）由位于美国加利福尼亚州山景城的美国国家航空航天局（National Aeronautics and Space Administration, NASA）艾姆斯研究中心机载传感器设施维护并运营，受NASA戈达德太空飞行中心地球观测系统（Earth Observing System, EOS）项目科学办公室监管。1995年以前，中分辨率成像光谱仪机载模拟器（Moderate Resolution Imaging Spectroradiometer Airborne Simulator, MAS）曾搭载于NASA的ER-2与C-130航空器平台，彼时采用的12通道8位数据系统一定程度上限制了这款50通道扫描光谱仪的全部性能潜力。自1995年1月起，ER-2平台开始搭载50通道16位数字化器，该
