AB: We have developed a simple, yet complete bio-optical model for the inherent optical properties (IOPs) of oceanic waters. This bio-optical model is specifically designed for use in comprehensive, multiple scattering radiative transfer models for the coupled atmosphere-ocean system. The advantage of this bio-optical model is that it can be employed to construct algorithms for simultaneous retrieval of aerosol optical properties and concentrations of oceanic water components. A retrieval algorithm was constructed by computing the remote sensing reflectance R_rs(λ) and validating it against simultaneous field measurements of R_rs(λ) and chlorophyll concentrations obtained from the SeaBASS data base. We present results from tests showing that the algorithm yields reliable retrieval results for a large range of chlorophyll concentrations. Similar tests of a MODIS/VIIRS chlorophyll retrieval algorithm show that its overall performance is less satisfactory. Based on the one-component bio-optical model, we have further developed a two-component bio-optical model, which includes phytoplankton and Chromophoric Dissolved Organic Matter (CDOM). This model enables simultaneous retrieval of chlorophyll concentration and the absorption coefficient for CDOM at 443 nm. We present results from a retrieval algorithm utilizing this two-component bio-optical model.
