Abstract
    This paper describes the validation of MERIS water products for Belgian waters for the period July 2002 to August 2005. During this period, 23 match-ups were obtained for the parameters, water-leaving reflectance spectra, chlorophyll a concentration and total suspended matter concentration, of which 7 are in optimal conditions. The water-leaving reflectance comparison shows good agreement in green and red bands but worse in blue bands, which might indicate the need for further improvement in estimation of the spectral slope of aerosol reflectance. The chlorophyll concentration analysis is inconclusive due to the limited range of the case 2 chlorophyll in the match-ups while the total suspended matter error is about 59% for match-up data. Finally, comparison of two MERIS processors shows that improvements are necessary in atmospheric correction at highly turbid pixels and in chlorophyll image quality.
