Sentinel-3 Top-Of-Canopy Reflectance 2018-present (raster 300m), global, daily - version 2

The surface reflectance is the Top-Of-Canopy (TOC) reflectance derived from the Top Of
Atmosphere (TOA) reflectance after correction for the temporally, spatially and spectrally varying
scattering and absorbing effects of atmospheric components.
The Sentinel-3 Top-Of-Canopy (TOC) reflectances are the common input to derive the Sentinel-3 based global bio-geophysical products.
Compared to the previous version, the version 2 benefits from an improved OLCI-SLSTR co-registration and a better cloud, snow and cloud shadow discrimination. Furthermore, the calibration correction factors are applied on the SLSTR data and on the OLCI-A data, as recommended by ESA. Finally, uncertainties are associated to the spectral TOC reflectances, propagating the uncertainty of original OLCI input data and taking into account the uncertainty due to the aerosol model.
