MISR Level 3 Daily FIRSTLOOK Component Global Albedo Product V002Entry ID: MI3DALF2
Abstract: The MISR Level 3 FIRSTLOOK Component Global Albedo Product covering a day contains a statistical summary of column albedo 555 nanometer optical depth, and a monthly aerosol compositional type frequency histogram. This data product is a global summary of the Level 2 albedo parameters of interest averaged over a day and reported on a geographic grid, with resolution of 1 degree by 1 degree and 5 ... degree by 5 degree.
The 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 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 7 minutes for all ninecameras 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.
