1 Data information
For the Global Ocean Satellite Observations’, ACRI-ST company (Sophia Antipolis, France) is providing Chlorophyll-a and Optics products - present based on the Copernicus-GlobColour processor.
Chlorophyll and Bio products refer to Chlorophyll-a, Primary Production (PP) and Phytoplankton Functional types (PFT). Products are based on a multi sensors/algorithms approach to provide to end-users the best estimate. Two dailies Chlorophyll-a products are distributed:
- one limited to the daily observations (called L3),
- the other based on a space-time interpolation: the “Cloud Free” (called L4).
Optics products refer to Reflectance (RRS), Suspended Matter (SPM), Particulate Backscattering (BBP), Secchi Transparency Depth (ZSD), Diffuse Attenuation (KD490) and Absorption Coef. (ADG/CDM).
The spatial resolution is 4 km. For Chlorophyll, a 1 km over the Atlantic (46W-13E , 20N-66N) is also available for the Cloud Free product, plus a 300m Global coastal product (OLCI S3A & S3B merged). Products (Daily, Monthly and Climatology) are based on the merging of the sensors SeaWiFS, MODIS, MERIS, VIIRS-SNPP&JPSS1, OLCI-S3A&S3B. For OLCI-S3A, products are also delivered as a single sensor. Recent products are organized in datasets called NRT (Near Real Time) and long time-series in datasets called REP/MY (Multi-Years). The NRT products are provided one day after satellite acquisition and updated a few days after in Delayed Time (DT) to provide a better quality. An uncertainty is given at pixel level for all products.
