Paper Abstract

SeaDAS proposes the water leaving radiance as a level 2 product for the SeaWiFS sensor. This radiance results from the Gordon & Wang atmospheric correction scheme, applied on the measured Top Of Atmosphere radiance. We have access to ground-based measurements acquired by the CIMEL instrument at the SeaWiFS time overpass in different locations over European coastal waters. An in-house software package has been developed in order to derive from the CIMEL data the required inputs (optical thickness and phase function) to a radiative transfer code (RTC). Computations allow to retrieve the SeaWiFS water leaving radiances with the “actual” atmospheric optical properties. An extended comparison between these values and those proposed by SeaDAS is conducted.
