The OMAERUV algorithm uses OMI measured reflectances at 354 and 388 nm to retrieve atmospheric column values of aerosol optical depth, single scattering albedo, and absorbing aerosol index at a 13x24 km nadir spatial resoltion. Ancillary data on CO and aerosol layer height from A-train sensors AIRS and CALIPSO are used in the retrieval. The algorithm is explained in detail in the document that can be found by following the Algorithm Description link below.
