    • MISR OBC Data V002

    Metadata Updated: September 19, 2025

    MI1AOBC_2 is the Multi-angle Imaging SpectroRadiometer (MISR) OBC Data version 2. This file contains the output for the Level 1A On-board Calibrator Data, and it provides the radiometry from PIN and HQE diodes and goniometer mechanism readings collected during calibration mode operations near the north and south poles and over the dark side of the Earth (or during science mode operations over the sunlit side of the Earth). The diode radiometry acquired during the north and south pole calibration sequences will be used to determine an MISR diffuser panel's brightness and reflective characteristics as observed by each of the nine MISR cameras. The MISR instrument consists of nine push-broom cameras that measure radiance in four spectral bands. Global coverage is achieved in nine days. The cameras are arranged with one camera pointing toward the nadir, four forward, and four aftward. It takes seven minutes for all nine cameras to view the same surface location. The view angles relative to the surface reference ellipsoid are 0, 26.1, 45.6, 60.0, and 70.5 degrees. The spectral band shapes are nominally Gaussian, centered at 443, 555, 670, and 865 nm.
