The Ocean Colour - Climate Change initiative (OC-CCI) datasets include all default light reflectance bands used to produce chlorophyll maps. To accompany these data we also host and make available two sets of uncertainty data per base variable. This gives access to not only the data itself but also to the quality assesment of the data. The data can be combined in novel and useful ways, for instance; to provide statistics on the uncertainty of the data or selecting final products where an average uncertainty is below a threshold.
In the coming months we will be making ESA Sentinel 3 Ocean Colour data available through the service. You can follow the progress of the completion and launch of Sentinel 3 here
