Abstract
We report on a number of radiative transfer calculations that have been performed in order to predict Medium Resolution Imaging Spectrometer (MERIS) measurements for the anticipated spectral bands and observation geometries for selected open ocean and coastal waters. The simulations show that, above coastal waters, significant levels of the water-leaving radiance must be expected in several of the MERIS channels dedicated to the atmospheric correction. These channels should be included in the algorithms to retrieve concentrations of water constituents. In addition, sunglint may affect large parts of MERIS satellite images, especially in the lower latitudes between ca 20 N and 20 S. Radiative transfer calculations similar to those presented here are used to derive algorithms for the assessment of constituent concentrations in Case II waters from ocean colour measurements.
