Atmospheric Correction for Remotely-Sensed Ocean-Colour.

Abstract

Atmospheric correction is a key procedure in remote sensing of ocean colour. This report provides an overview of the various atmospheric correction algorithms used for global ocean-colour data processing, and quantifies the performance of operational atmospheric correction algorithms for SeaWiFS, MODIS-Aqua, MERIS, OCTS, GLI and POLDER. The performance of the various algorithms is compared using common simulated data sets, mainly for open ocean (Case-1) waters and for non- or weakly-absorbing aerosols. Examples from coastal Case-2 waters (sediment-dominated and yellow-substance dominated waters) and from strongly-absorbing aerosols are also provided and discussed.
