NEW DATA: Ocean Colour version 4 Dataset Release

Ocean Colour version 4 Dataset Release


The latest version of the Ocean Colour_cci dataset version 4.0 is available.

The dataset now extends across two decades to the end of December 2018 and is an update of the version 3.1 product that includes NASA's most recent reprocessing (R2018) updates for MODIS-Aqua, VIIRS and SeaWiFS.  This included significant recalibration for MODIS to address noticeable drift in trends resulting from sensor decay.

The data comprise globally merged MERIS, Aqua-MODIS, SeaWiFS and VIIRS data with associated per-pixel uncertainty information.
