NASA TROPOMI Aerosol Products: Current Status and Ongoing Developments

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. The N-TropOMAER algorithm benefits from TROPOMI's unprecedented fine spatial resolution at UV wavelengths (3.5X5.5 km) that allows for improved accuracy of retrieved aerosol parameters. In this presentation we will discuss the current status of the N-TropOMAER including validation and applications. We will also introduce the second-generation UV-VIS algorithm that includes retrieval capability in the visible, and derivation of aerosol layer height (ALH) using TROPOMI O2B band observations. The improved algorithm will also be applied to observations by other sensors including the currently operating L1 Earth Panchromatic Imaging Camera (EPIC) instrument and to the soon-to-be launched Tropospheric Emissions: Monitoring of Pollution (TEMPO) sensor on the IS40e geostationary satellite.
