Paper Abstract

High quality in situ radiometric observations is needed for calibration, validation, and bio-optical algorithm development of ocean color remote sensing, moreover in studying and understanding of ocean optical, biological, and biogeochemical properties. Notably, calibration and validation of ocean color satellite data depend on high quality in situ data. Therefore, to improve our understanding of optical properties of the Red Sea, radiometric field measurements performed during in 2016 oceanographic cruises. The data set measured using the SatlanticTM HyperPro instrument equipped with radiometers, includes downwelling irradiance (Ed), upwelling radiance (Lu), and surface reference irradiance (Es). Profiles of downwelling irradiances were used to calculate diffuse attenuation coefficient, the first optical depth, PAR, and depth of the euphotic zone. Remote sensing reflectance computed from the ratio of upwelling radiance to downwelling irradiance. Derivative analysis performed on the spectral remote sensing reflectance to identify the different phytoplankton pigments based on the various peaks. The results obtain from the observational data analysis will be presented in this paper and discussed for ocean color implications.
