Abstract:
The Multi-Angle Imaging SpectroRadiometer (MISR), to be launched in 1998, is one of five instruments on NASA's first Earth Observing System (EOS) platform. The 3% absolute radiometric calibration requirement is considered challenging, particularly since it must be maintained through the five-year mission life. The Instrument requirements have led to the development of an On-Board Calibrator (OBC) consisting of diffuse panels and photodiode-based radiometric standards.
