OMI OMAERO
 |
 |
The OMAERO Level 2 data product contains aerosol characteristics such as aerosol optical thickness (AOT), aerosol type, aerosol absorption indices as well as ancillary information. The aerosol optical thickness is retrieved from OMI spectral reflectance measurements and a best fitting aerosol type is determined. The single-scattering albedo, the layer height and the size distribution associated with the best fitting aerosol type are provided as well as diagnostic information.
