OLCI Level 2 CHL Concentration Daily Accumulated - Sentinel-3
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 S3 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.
Full details of the chl_oc4me algorithm can be found in the case 1 resource link.
The image is an incrementally accumulated product of all the orbits over an entire day from both Sentinel-3A and -3B.
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).
