Abstract :
HYPERspectral Tethered Spectral Radiometer Buoy (Hyper-TSRB, Satlantic Inc.) has 123 channels from 400 nm to 800 nm to measure downwelling irradiance (Ed) and upwelling radiance (Lu ). The supplied software for Hyper-TSRB data processing (AKA, PROSOFT) is based on Case I and/or empirical algorithms. In this paper, a new semi-analytical method is proposed for Level 3 data processing. Basically, for open oceans case I waters, no large differences are found between the new method and PROSOFT (~10%); while for coastal case II waters, the new method is much better than PROSOFT in computed remote sensing reflectance (~10%-350%). The effect of phase function to the new method is also analyzed, it is shown that the new method can work stably for a wide phase function ranges
