Abstract

Sun glint, defined as solar irradiance which is reflected at the sea surface, is a major problem for ocean colour remote sensing. Since MERIS has no tilt mechanism, observations are often affected by sun glint, depending on wind speed and observation geometry. To extend the area of a MERIS scene that can be used for ocean colour observations, a new atmospheric and sun glint correction algorithm is under development. MERIS and AATSR measurements provide information of visible and near infrared reflected as well as emitted radiation at 11 and 12mm. AATSR also observes the Earth in nadir and forward views. The new algorithm takes advantage of MERIS and AATSR capacities.

First results of sun glint corrected MERIS scenes will be presented.

This work was supported under ESA/ESRIN contract AO/1-5232/06/I-OL.
