MISR Level 3 Monthly FIRSTLOOK Global Aerosol Product in netCDF format V002Entry ID: MI3MAENF2
Abstract: The MISR Level 3 FIRSTLOOK Global Aerosol Product in netCDF format covering a month contains a statistical summary of column aerosol 555 nanometer optical depth, and a monthly aersosol compositional type frequency histogram. This data product is a global summary of the Level 2 aerosol parameters of interest averaged over a month and reported on a geographic grid, with resolution of 0.5 degree by ... 0.5 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.
