SIMULTANEOUS RETRIEVAL OF AEROSOLS AND MARINE CONSTITUENTS IN COASTAL WATERS
A new method for simultaneous retrieval of aerosol properties and marine constituents in turbid waters is described. This method is an extension to turbid waters of an approach developed previously for simultaneous retrieval of aerosol properties and chlorophyll concentrations in clear waters. This...
