    Parameters to be used to generate inherent optical properties for the oceanic and atmospheric components

    The specifications provided in this document define the parameters to be used to generate inherent optical properties for the oceanic and atmospheric components 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 reflectances or total reflectances at top of the atmosphere level). Parameters have been selected from various measurements and models in water, surface and atmosphere. The underlying geo-physical models are the same as those of the MERIS geophysical algorithms, as described in the MERIS Algorithm Theoretical Basis Document (ATBD) PO-TN-MEL-GS-0005 (Iss. 4.1).

    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.
