OLCI Level 2 CHL Concentration - Sentinel-3A

Abstract:
This Ocean Colour product represents the algal pigment (Chlorophyll a) concentration in clear open waters, and it is defined by the "OC4Me" Maximum Band Ratio (MBR) semi-analytical algorithm. The product is derived from S3A OLCI L2 NRT water-leaving reflectances (calculated from the Baseline Atmospheric Correction). A maximum band ratio approach is used for reflectances at 443, 490 and 510 nm, over that 560 nm (O3 to O6). It is expressed in Units of mg/m3 as: log10 [Chl]= ∑4 x=0 =(Ax * (log10(Rij))x) which is the ratio of reflectance of band i, among 443, 490 and 510 nm, over that of band j at 560 nm. The following flags were applied: INVALID, LAND, CLOUD, CLOUD_AMBIGUOUS, CLOUD_MARGIN, SNOW_ICE, SUSPECT, HISOLZEN, SATURATED, HIGHGLINT, WHITECAPS, AC_FAIL, OC4ME_FAIL, ANNOT_TAU06, RWNEG_O2, RWNEG_O3, RWNEG_O4, RWNEG_O5, RWNEG_O6, RWNEG_O7 and RWNEG_O8. Full details of the chl_oc4me algorithm can be found in the case 1 resource link. Sentinel-3 is part of a series of Sentinel satellites, under the umbrella of the EU Copernicus programme. This product can be downloaded as numerical data in EUMETView NG, where it is provided through a Web Coverage Service (WCS).
