Abstract
The ESA Ocean Colour CCI project has produced global level 3 binned multi-sensor time-series of satellite ocean-colour data with a particular focus for use in climate studies.
This dataset contains a monthly climatology of the generated ocean colour products.
Data products being produced include: phytoplankton chlorophyll-a concentration; remote-sensing reflectance at six wavelengths; total absorption and backscattering coefficients; phytoplankton absorption coefficient and absorption coefficients for dissolved and detrital material; and the diffuse attenuation coefficient for downwelling irradiance for light of wavelength 490nm. Information on uncertainties is also provided.
Please note, this dataset has been superseded. Later versions of the data are now available.

| Title | Derivation of Ocean Colour v4 data from the ESA Climate Change Initiative Ocean Colour project (Ocean_Colour_cci) |
| Abstract | The ocean colour CCI has calculated ocean colour Essential Climate Variable data, using input data from various satellite instruments, as part of the ESA Climate Change Initiative program. The v4 dataset has been created by band-shifting and bias-correcting MERIS, MODIS and VIIRS data to For more information see the Ocean Colour v4 Product User Guide. |
