Description

Chlorophyll-A data from ESA’s GlobColour project is available as a local copy for internal KlimaCampus use. Product: chlorophyll-a, weighted, monthly means in 1° (index 100) and 0.25° (index 25) resolution.

The GlobColour service distributes global daily, 8-day and monthly data sets at 4.6 km resolution for, chlorophyll-a concentration, normalized water-leaving radiances (412, 443, 490, 510, 531, 555 and 620 nm, 670, 681 and 709 nm), diffuse attenuation coefficient, coloured dissolved and detrital organic materials, total suspended matter or particulate backscattering coefficient, turbidity index, cloud fraction and quality indicators. Error statistics from the initial sensor characterization are used as an input to the merging methods and propagate through the merging process to provide error estimates for the output merged products. These error estimates are a key component of GlobColour as they are invaluable to the users; particularly the modellers who need them in order to assimilate the ocean color data into ocean simulations. See the Product User Guide (PUG) for further details on the GlobColour products.
