MISR FIRSTLOOK radiometric camera-by-camera Cloud Mask V001

Version 001
  • Abstract
    Multi-angle Imaging SpectroRadiometer (MISR) is an instrument designed to view Earth with cameras pointed in 9 different directions. As the instrument flies overhead, each piece of Earth's surface below is successively imaged by all 9 cameras, in each of 4 wavelengths (blue, green, red, and near-infrared). The goal of MISR is to improve our understanding of the fate of sunlight in Earth environment, as well as distinguish different types of clouds, particles and surfaces. Specifically, MISR monitors the monthly, seasonal, and long-term trends in three areas: 1) amount and type of atmospheric particles (aerosols), including those formed by natural sources and by human activities; 2) amounts, types, and heights of clouds, and 3) distribution of land surface cover, including vegetation canopy structure. MISR FIRSTLOOK radiometric camera-by-camera Cloud Mask V001 contains the FIRSTLOOK Radiometric camera-by-camera Cloud Mask (RCCM) dataset produced using ancillary inputs Radiometric Camera-by-camera Cloud mask Threshold (RCCT) from the previous time period. It is used to determine whether a scene is clear, cloudy or dusty (over ocean).
  • Purpose
    The Radiometric camera-by-camera Cloud Mask (RCCM) is used during geophysical parameter retrievals. In the Top of the Atmosphere (TOA)/Cloud Product, RCCM is combined with stereoscopically derived cloud mask to 1) establish values of the Reflecting Level Reference Altitude, 2) determine how a scene is classified for choosing angular integration coefficients for establishing TOA albedos, and 3) calculate regional scene classifiers. Retrieval of Aerosol/Surface Product properties requires the absence of clouds, for retrieval assumptions to be valid.
