Improvement of MERIS level 2 products in Baltic Sea coastal areas by applying the Improved Contrast between Ocean and Land processor (ICOL) - data analysis and validation

In this paper we compare the followingMERIS processors against sea-truthing data:the standard MERIS processor (MEGS 7.4.1), the Case 2Regional processor (C2R) of the German Institutefor Coastal Research (GKSS), and the Case 2Water Properties processor developed at the FreieUniversität Berlin (FUB). Furthermore, the ImprovedContrast between Ocean and Land processor (ICOL), a prototypeprocessor for the correction of adjacency effects from land,was tested on all three processors, and the retrieval of level 2data was evaluated against sea-truthing data before and afterICOL processing.
