C2RCC Processor

Overview

The Case 2 Regional CoastColour (C2RCC) atmospheric correction is a full spectrum version using a set of neural networks which are trained on simulated top-of-atmosphere reflectance. The raditiave transfer simulations include the full ocean and atmosphere system, i.e. a specific water model is included in the simulations. C2RCC is used to generate the Case 2 water products in Sentinel 3 OLCI standard ESA products, as well as in the upcoming MERIS 4th Reprocessing. Products generated are the inherent optical properties (IOPs), absorption and scattering of the different constituents; the three major optically relevant concentrations, i.e. phytoplankton pigments, total suspended matter and yellow substance; and their related uncertainties.
It supports several sensors: starting from Sentinel-3 OLCI over Sentinel-2 MSI to Landsat-8 OLI and the heritage sensor MERIS, both in 3rd and 4th reprocessing versions. MODIS, VIIRS and SeaWiFS are supported as well.
