摘要: The Terra spacecraft contains five Earth-observation instruments, three of which are multispectral imaging sensors that complement each other in spectral and spatial coverage. Moderate Resolution Imaging Spectroradiometer (MODIS) has 36 channels ranging from 0.4–14.4 μm, with resolutions 250, 500, 1000 m. Multi-angle SpectroRadiometer (MISR) uses individual to view the earth at nine discreet angles. Each radiometer four visible near infrared (VNIR), nadir-viewing camera a resolution 275 Advanced Spaceborne Thermal Emission Reflection Radiometer (ASTER) was designed fourteen bands 0.5–11.6 μm. It is high-resolution sensor on Terra, 15 m VNIR, 30 shortwave (SWIR). This work describes vicarious techniques used perform absolute radiometric calibration MODIS, MISR, ASTER solar-reflective region (0.4–2.5 μm). includes reflectance-based approach, ground-based personnel make situ measurements during time overpass. also more recent results were obtained using University Arizona’s automated Radiometric Calibration Test Site (RadCaTS) Railroad Valley, Nevada. In addition sensors, RadCaTS cross comparison Landsat 7 ETM+ 8 OLI.
