The NASA S5P-TROPOMI (Sentinel 5 Precursor-Tropospheric Monitoring Instrument) aerosol algorithm (N-TropOMAER) extends the continuous 17-year record of near UV aerosol properties started by the Aura Ozone Monitoring Instrument (OMI) in 2005.  Aerosol optical depth (AOD) and single scattering albedo (SSA) for clear sky conditions and above-cloud aerosol optical depth (ACAOD) are retrieved.  In this presentation we will describe a second-generation UV-VIS algorithm that includes retrieval capability in the visible, and derivation of aerosol layer height (ALH) using TROPOMI O2B band observations. We will also discuss recent theoretical advances that allow extending retrieved aerosol absorption information in the ultraviolet to the visible. Initial results and comparison to other satellite and ground-based observations will be presented.
