For the Global Ocean, climatology of the chlorophyll-a concentration for case 1 water (expressed in mg/m3). The climatology is based on the GlobColour (http://www.globcolour.info) products obtained by the merging of MERIS MODIS and SeaWIFS data available during the period 1998-2009. The "Number of data" product represents for each pixel, the number of data available when computing the chlorophyll-a concentration product by merging for each of the 12 years the selected month (April). Depending of the location of the pixel, the number of data varies from 0 to 12. The spatial resolution of the product is about 4km. The product has been designed and produced by ACRI-ST INFOCEAN-DESK environment monitoring service from EU FP7 & ESA MyOcean GlobColour Products, ESA ENVISAT MERIS data, NASA MODIS and SeaWiFS data. The GlobColour project has been initiated and funded by the ESA Data User Element Programme to develop a satellite based ocean colour data service to support global carbon-cycle research. The GlobColour project has largely benefited from NASA contributions, including the availability of the MODIS and SeaWiFS products; the in situ data base of radiometric and phytoplankton pigment data, and other oceanographic and atmospheric data: the SeaWiFS Bio-optical Archive and Storage System - SeaBASS (Werdell and Bailey, 2002). The global merged chlorophyll-a concentration for case 1 water is obtained by the merging of MERIS, MODIS and SeaWiFS data using an advanced retrieval based on fitting an in-water bio-optical model to the merged set of observed normalised water-leaving radiances (nLw?s). This technique is termed GSM because it originates from the Garver et al. (1997) bio-optical model (Maritorena and Siegel, 2005).

The climatology is based on the GlobColour (http://www.globcolour.info) products obtained by the merging of MERIS MODIS and SeaWIFS data available during the period 1998-2009. The mean value product represents the mean chlorophyll-a concentration obtained by merging for each of the 12 years the selected month (April). The spatial resolution of the product is about 4km.

Over the Chile, climatology of the chlorophyll-a concentration for case 1 water (expressed in mg/m3). The climatology is based on the GlobColour (http://www.globcolour.info) products obtained by the merging of MERIS MODIS and SeaWIFS data available during the period 1998-2009. The "April 2003 Anomaly" product represents for each pixel, the difference between the chlorophyll-a concentration product by merging for each of the 12 years the considered month (April) and the chlorophyll-a concentration observed in April 2003. The difference is expressed as a percentage of change ''(April 2003 �?? April 1998-2009) / April 1998-2009". The spatial resolution of the product is about 4km. The product has been designed and produced by ACRI-ST INFOCEAN-DESK environment monitoring service from EU FP7 & ESA MyOcean GlobColour Products, ESA ENVISAT MERIS data, NASA MODIS and SeaWiFS data.
