Abstract :
A procedure for an accurate atmospheric correction for ocean color remote sensing is described. It is shown that an appropriate aerosol model is the key factor for pursuing the atmospheric correction, including multiple scattering light in the atmosphere-ocean system. An algorithm for estimating the aerosol models suitable for the Nimbus-7 CZCS image of interest is proposed. As a result, phytoplankton pigment concentration near the sea surface is derived through the atmospheric correction and biooptical algorithms. The treatment is found to provide an improved pigment map of the sea surface near Japan
