OLCI Level 2 Ocean Colour Reduced Resolution - Sentinel-3

OLCI (Ocean and Land Colour Instrument) Ocean Colour Geophysical Products. Reduced Resolution: 1200m at nadir. Level 2 marine products include the following: * water-leaving reflectances in 16 bands, Oa**_reflectance (Baseline Atmospheric Correction (BAC) algorithm, bands: 400, 412, 442, 490, 510, 560, 620, 665, 674, 681, 709, 754, 779, 865, 885, 1024 nanometer (nm)); *algal pigment concentration in clear waters, chl_oc4me (BAC and maximum band ratio algorithm, log10 scaled); *algal pigment concentration in turbid waters, chl_nn (neural net algorithm, log10 scaled); *total suspended matter concentration, tsm_nn (neural net algorithm, log10 scaled); *diffuse attenuation coefficient Kd of downward irradiance at 490 nm, trsp (BAC and M07 algorithm, log10 scaled); *absorption coefficient at 443 nm of coloured detrital and dissolved organic matter, iop_nn (neural net algorithm, log10 scaled); *instantaneous photosynthetically active radiation, PAR (BAC and clear-sky ocean algorithm); *aerosol optical thickness T865 and aerosol Angstrom exponent A865, w_aer (BAC algorithm, A for bands 779 and 865 nm) *integrated water vapour column, iwv (1D-Var algorithm). The geophysical products are accompanied by error estimate products. Pixel classification, quality and science flags, as well as meteorological, geometry and geolocation data at tie points are provided. - All Sentinel-3 NRT products are available at pick-up point in less than 3h - All Sentinel-3 Non Time Critical (NTC) products are available at pick-up point in less than 30 days. Sentinel-3 is part of a series of Sentinel satellites, under the umbrella of the EU Copernicus programme.
