Ocean Products
This product, OL_2_WFR / OL_2_WRR (for full and reduced resolution respectively), is composed of 24 measurement files containing:
- reflectance files (16 files), containing the water-leaving reflectance for all bands except those dedicated to measurement of atmospheric gas (Oa13, Oa14, Oa15, Oa19, and Oa20) absorption
- OC4Me Chlorophyll concentration file
- neural net Chlorophyll concentration file
- neural net total suspended matter concentration file
- transparency products file
- a neural net water inherent optical properties file
- a photosynthetically active radiation file
- aerosol over water file
- integrated water vapour over water file.
The following table gives the full content of the OLCI water Level-2 product. Note that the annotation files are common to the land product and the OLCI Level-1B product.
