Description
This Level-2G daily global gridded product OMAEROG is based on the pixel level OMI Level-2 Aerosol product OMAERO, based on the multi-wavelength algorithm that uses up to 20 wavelength bands between 331 nm and 500 nm. OMAEROG is a special Level-2 gridded product where pixel level products are binned into 0.25 x 0.25 degree global grids. It contains the data for all scenes that have observation time between UTC times of 00:00:00 and 23:59:59.9999. All data pixels that fall in a grid box are saved without averaging. Scientists can apply a data filtering scheme of their choice and create new gridded products.
The OMAEROG data product contains almost all parameters that are in OMAERO. For example, in addition to the extinction optical depth and single scattering albedo, it also contains aerosol indices, cloud fraction, cloud pressure, terrain height, geolocation, solar and satellite viewing angles, and extensive quality flags.
The OMAEROG files are stored in the version 5 EOS Hierarchical Data Format (HDF-EOS5). Each file contains daily data from approximately 15 orbits. The maximum file size for the OMAEROG data product is about 78 Mbytes.
