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 + consolidated products)
  • 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 NPP, OLCI-A, VIIRS JPSS-1 and OLCI-B (OLCI-A/B and VIIRS JPSS-1 are not merged with other sensors for all parameters for the moment)
