  • Validation Report following the 3rd MERIS data reprocessing

    This document prepared by the MERIS Quality Working Group (QWG) corresponds to the Validation Report following the 3rd MERIS data reprocessing. It aims at qualifying and quantifying the accuracy of the MERIS L2 products generated with the version 8.0 of MERIS Ground Segment prototype (MEGS), delivered to the whole community through the ODESA software (http://earth.eo.esa.int/odesa/). It is equivalent to version 6.0 of the Instrument Processing Facilities (IPF) at ESRIN.
