    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.

    Reference Model for MERIS Level 2 Processing

    The specifications provided here define the parameters to be used to generate inherent optical properties for the ocean and atmosphere as a function of geophysical properties and wavelengths, which can be the basis upon which to generate test data and auxiliary parameters needed for operation and end-to-end tests of the MERIS ground segment processor (i.e., mostly to generate water-leaving reflectances or total reflectances at the top of the atmosphere level). Parameters have been selected from various measurements and models in water, surface and atmosphere.
