Archive


The GlobColour Archive data consists of daily, weekly and monthly Level-3 ocean colour products generated at day+15. The archive data (September 1997 - present) is based on the merging of MERIS, SeaWiFS and MODIS level-2 data over the whole globe as per availability. The best resolution of the archive products is 4.6km. Extraction over user defined areas is available.

Near Real Time

The GlobColour Near Real Time (NRT) data consists of daily and weekly Level-3 ocean colour products generated at day+1. The NRT service is currently based on the MODIS level-2 data over the whole globe. The resolution of the NRT products is 4.6km. Extraction over user defined areas is available.

Service on demand

The Service on-demand allows any user to systematically obtain NRT products at a 1 km resolution (or larger) over any local area. Requests can be updated a-posteriori thanks to an identifier send to the user by email. Try it! Should you be interested in past merged products at 1km resolution over your specific region of interest, please contact: service@globcolour.info

NRT rolling archive

Near Real Time products can also be downloaded from a 15-days rolling archive. Only global products (FPS) are available. wget them!
