Short summary
This paper concerns the GlobColour chlorophyll α products disseminated by the Copernicus Marine Environmental Monitoring Service (CMEMS). The strategies for merging and flagging remote-sensing data are discussed. Results are illustrated by comparing the CMEMS GlobColour products provided by ACRI-ST with the OC-CCI/C3S products. This highlights the capability of GlobColour to obtain a better spatial coverage and to ingest the OLCI data in complement with SeaWiFS, MERIS, MODIS and VIIRS sensors.
