OLCI-S3A Animation Merged Daily Merged Monthly


The GlobColour data set provides a large set of Ocean Colour products:
  • Parameters: Chlorophyll concentration, Secchi Disk Depth, and many more…
  • Time coverage: from 1997 to present (Near Real Time at day + 15)
  • Time resolution: daily, weekly and monthly products
  • Spatial Coverage and resolution: Global at 4, 25 and 100 km, Europe at 1 km, and user-defined extraction zones
  • Sensors: single sensor and merged products from SeaWIFS, MERIS, MODIS, VIIRS and OLCI-A (OLCI is not merged with other sensors for the moment)
