L3 products are daily files, while the L4 are monthly composites. Processing of these data was mainly carried out in the OC-CCI framework producing a climate-quality consistent dataset using the latest and most complete knowledge of satellite sensor calibration, characterization and attitude, complete (as far as possible) ancillary data sets, latest versions of models and algorithms etc. The data were then repackaged, using custom software, to suit the requirements of CMEMS. The remote sensing of Ocean Colour represents a measure of the spectral variations in the light leaving the water surface, subsequently interpreted in terms of concentrations of optically-significant constituents in the water. The electromagnetic signal collected by the sensor on-board the satellite is largely determined by photons that have never reached the water surface, but have been backscattered within the atmosphere through multiple interactions between gas molecules and aerosols. After removing the atmospheric contribution, the water leaving radiance recorded at a given time by the satellite reflects the optical properties of the water which, in turn, mirrors a specific structure and biogeochemical composition of the marine waters. A detailed description of calibration & validation is given in the relevant QUID, associated validation reports and quality documentation.
