Ocean color remote sensing is an important tool to monitor water quality and biogeochemical conditions of ocean. Atmospheric correction, which obtains water-leaving radiance from the total radiance measured by satellite-borne or airborne sensors, remains a challenging task for coastal waters due to the complex optical properties of aerosols and ocean waters. In this paper, we report a research algorithm on aerosol and ocean color retrieval with emphasis on coastal waters, which uses coupled atmosphere and ocean radiative transfer model to fit polarized radiance measurements at multiple viewing angles and multiple wavelengths. Ocean optical properties are characterized by a generalized bio-optical model with direct accounting for the absorption and scattering of phytoplankton, colored dissolved organic matter (CDOM) and non-algal particles (NAP). Our retrieval algorithm can accurately determine the water-leaving radiance and aerosol properties for coastal waters, and may be used to improve the atmospheric correction when apply to a hyperspectral ocean color instrument.
Orange-Mint leaves juice was formulated using different addition percentages of mint leaves extract. The juice was aseptically processed, packed in glass bottles under sterilized environment and sterilized at 70C for 15 minutes then storage at 5C for 3 months. The physicochemical, nutritional value, microbiological and sensory characteristics of the juice was evaluated. There is no difference in pH, total soluble solids, ash, and total acidity in all samples moreover, the sample A2, "orange juice with 15% of mint leaves extract" recorded the best values of sensory evaluation, on the other hand, it was recorded lower values of vitamin C and total phenolic compound than sample (C) or (C1) because of increasing in addition% of mint leaves extract to orange juice. The sensory properties of juice samples were not remarkable any changes during storage. The result indicated that the juice was acceptable up to 3 months of storage 5C.
