MISR L2 Aerosol Product subset for the C-MARE Region V002

Published by NASA/LARC/SD/ASDC;NASA/JPL/MISR | National Aeronautics and Space Administration | Catalog Last Checked: May 18, 2026 at 03:21 PM | Dataset Last Updated: May 11, 2026
CMRMIAAE_2 is the Multi-angle Imaging SpectroRadiometer (MISR) Level 2 Aerosol Product subset for the C-MARE Region version 2. It contains aerosol optical depth, ancillary meteorological data, and related parameters on a 17.6 km grid for the CMARE_2004 theme. To study the magnitude and natural variability in space and time of sunlight and cloud interactions with aerosols in the earth's atmosphere and to determine their effect on climate; to improve knowledge of sources, sinks, and regional budgets of aerosols; and to provide atmospheric correction inputs for surface imaging data acquired by MISR and other instruments that are simultaneously viewing the same portion of the Earth, to make better quantitative estimates of surface reflectance. 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.
