Abstract

Near-UV and visible observations by the Ozone Monitoring Instrument (OMI) on the AURA satellite are used in an inversion algorithm to retrieve aerosol extinction and absorption optical depth. The sensitivity to aerosol absorption, a unique capability of the OMI measurements,is based on the interaction of particle absorption and molecular scattering in the near-UV spectral region. OMI near-UV aerosol retrievals are obtained over the oceans and most land areas including deserts where traditional single view visible and near-IR retrieval methods fail. Results of the OMI near-UV aerosol algorithm will be discussed in the context of other satellite and ground-based measurements.
