Deep Space Climate Observatory Earth Polychromatic Imaging Camera Level 2 UV Aerosol Products

Abstract: The Aerosol UV product provides aerosol and UV products in three tiers. Tier 1 products include Absorbing Aerosol Index (AAI) and above-cloud-aerosol optical depth (ACAOD). Tier 2 includes a four-parameter retrieval algorithm combining of UV-VIS observations: aerosol optical depth (AOD), angstrom exponent (AE), near UV single scattering albedo (SSA), and effective aerosol layer height (ALH). Cloud masking will be carried out with collocated high resolution LEO observations. Tier 3 contains Experimental Products, including research work on using EPIC?s glint and off-glint observations to characterize spectral aerosol absorption. Tier 3 research includes ways of estimating the height of aerosol layers over the ocean using EPIC?s channels in the Oxygen-A and B bands.
