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 and VIIRS

Sensor types

Sensor Product type Start Date End Date Reprocessing
MERIS RR 1 km April 2002 April 2012 ESA 3rd reprocessing 2011
MODIS AQUA 1 km July 2002 Dec. 2010 NASA R2012.0
MODIS AQUA 1 km Jan. 2011 June 2015 NASA R2013.0
MODIS AQUA 1 km June 2015 present NASA R2014.0
SeaWIFS GAC 4km Sept. 1997 Dec. 2010 NASA R2010.0
VIIRS 1 km Jan. 2012 present NASA R2014.0
Warning: NASA has reported calibration issues for VIIRSN and MODIS-AQUA which can impact the quality of the time series after 2009. This is particularly significant for MODIS since 2012. See this discussion on the NASA forum for details.

Demonstration products

The OSS2015 demonstration products further increase the range of available parameters:
  • Chlorophyll concentration: new Color Index Algorithm from Hu et al. (2012)
  • New bio-chemical products: Particle Organic Carbon, Particle Size Distribution…
  • Time coverage: monthly merged products from 1997 to 2014
  • Spatial Coverage and resolution: Global products at 25 km resolution, with user-defined extraction zones
