MISR FIRSTLOOK radiometric camera-by-camera Cloud Mask V001

Published by NASA/LARC/SD/ASDC | National Aeronautics and Space Administration | Catalog Last Checked: May 06, 2026 at 06:27 PM | Dataset Last Updated: April 21, 2026
MIRCCMF_001 is the Multi-angle Imaging SpectroRadiometer (MISR) FIRSTLOOK radiometric camera-by-camera Cloud Mask (RCCM) version 1 data product. It was produced using ancillary inputs from the previous time period, such as Radiometric Camera-by-camera Cloud mask Threshold (RCCT). It is used to determine whether a scene is clear, cloudy, or dusty (over the ocean). Data collection for this product is ongoing. FIRSTLOOK processing uses the new time dependence of the Atmospheric and Surface Climatology (TASC) from the same month/previous year. The TASC data set now contains snow-ice and ocean surface wind speed values that are updated on a monthly basis. Therefore, these data sets cannot be generated until the end of the month. Products generated are distinguished by the presence of FIRSTLOOK in the file names. 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 cameras pointing forward, and four cameras pointing 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. MISR is designed to view Earth with cameras in 9 different directions. As the instrument flies overhead, all nine cameras successfully imaged each piece of Earth's surface below in 4 wavelengths (blue, green, red, and near-infrared). MISR aims to improve our understanding of the effects of sunlight on Earth and 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.
