A UNIVERSAL SEMIANALYTICAL MODEL FOR POLARIZED OCEAN REFLECTANCE IS PROPOSED WHICH WOULD INCORPORATE REFLECTANCE DUE TO WIDE RANGE OF BOTTOM DEPTHS BOTTOM ALBEDO REFRACTIVE INDICES OF ORGANISMS UNDER WATER PARTICLE PHASE FUNCTION PHYTOPLANKTON VARIETIES AND SEDIMENT CONCENTRATION AT DIFFERENT SOLAR ZENITH ANGLES AND WAVELENGTHS. BOTH POLARIZATION AND INELASTIC SCATTERING WILL BE INCLUDED. THE MAJOR INELASTIC SCATTERING MECHANISMS ARE RAMAN SCATTERING AND FLUORESCENCE FROM CHLOROPHYLL AND DISSOLVED ORGANIC MATTERS. THE STUDY OF POLARIZED REFLECTANCE HELPS TO DISTINGUISH HYDROSOLS BASED ON THEIR DIFFERENT PHYSICAL MORPHOLOGIES (SIZES AND SHAPES) AND DIELECTRIC PROPERTIES (REFRACTIVE INDEX). THE EFFECT OF VERTICAL DISTRIBUTION OF IOPS IN WATER COLUMN AND THE WIND SPEED ON THE WATER LEAVING RADIANCE WOULD ALSO BE EXPLORED TO INTERPRET GLOBAL OCEAN COLOR MEASUREMENTS. THIS WOULD LEAD TO A BETTER EXPLANATION FOR THE ECOLOGICAL AND BIOGEOCHEMICAL PROCESSES OF COASTAL AND OPEN OCEAN. THE SEMI-ANALYTICAL MODEL WILL BE VALIDATED USING RIGOROUS RADIATIVE TRANSFER SOLUTIONS TO THE COUPLED ATMOSPHERE AND OCEAN SYSTEMS. THIS WORK DIRECTLY TIES IN WITH THE WORK DONE BY NASA UNDER PACE (PRE-AEROSOL CLOUDS AND OCEAN ECOSYSTEM) MISSION TO DETECT THE HARMFUL ALGAL BLOOMS BY STUDYING THEIR SPECTRAL SIGNATURE. ALSO THIS MODEL WOULD INCLUDE UV WAVELENGTHS AND VISIBLE WAVELENGTHS WHICH WOULD HELP IN DIFFERENTIATING DISSOLVED ORGANIC MATERIAL FROM CHLOROPHYLL PRESENT IN UPPER PART OF OCEAN AND STUDY THE COASTAL AREAS. THE PROPOSED WORK WILL BE THE PRIMARY FIELD OF RESEARCH OF THE AUTHOR S PHD. DISSERTATION OVER THE THREE YEARS.
