Short Name:

MISR Level 3 Component Global Aerosol Product covering a year V004

MIL3YAE_4 is the Multi-angle Imaging SpectroRadiometer (MISR) Level 3 Component Global Aerosol Product covering a year version 4. It contains a statistical summary of column aerosol 555 nanometer optical depth, and a monthly aerosol compositional type frequency histogram. This data product is a global summary of the Level 2 aerosol parameters of interest averaged over a year and reported on a geographic grid, with resolution of 0.5 degree by 0.5 degree. The MISR instrument consists of nine pushbroom cameras which 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.
