Version 4 Dataset Release

The latest version of the OC-CCI dataset is 4.0 that comprises of globally merged MERIS, Aqua-MODIS, SeaWiFS and VIIRS data with associated per-pixel uncertainty information. This 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 dataset is periodically being updated, and the June 2019 release of version 4.0 extends the dataset to the end of December 2018.
