Abstract:

We examine the impact of incorrect atmospheric correction, specifically incorrect aerosol model selection, on retrieval of bio-optical properties from satellite ocean color imagery Uncertainties in retrievals of bio-optical properties such as chlorophyll, absorption and backscattering coefficients from satellite ocean color imagery are related to a variety of factors, including errors associated with sensor calibration, atmospheric correction, and the bio-optical inversion algorithms In many cases, selection of an inappropriate or erroneous aerosol model during atmospheric correction can dominate the errors in the satellite estimation of the normalized water-leaving radiances nLw, especially over turbid, coastal waters. These errors affect the downstream bio-optical properties Here, we focus on only the impact of incorrect aerosol model selection on the nLw radiance estimates, through comparisons between Moderate- Resolution Imaging Spectroradiometer MODIS satellite data and in situ measurements from AERONET-OC Aerosol Robotic NETwork - Ocean Color sampling platforms.
