New water quality parameters processed for 2002-2012

Processing of several new water quality parameters was conducted from MERIS data archive. Several L3 products, such as Chlorophyll, Visible Depth, Total Suspended Matter, and Turbidity, were processed with enhanced algorithms. Cloud detection could be improved. Exemplary, Figure 1 presents the Chlorophyll (CHL) concentration in the Bohai Sea for 2011 as aggregated monthly means. Figure 2 shows the Visible Depth (z90_max) for 2011 as monthly mean values. All water quality parameters were processed for the years 2002 to 2012. The spatial resolution of the information products is 300m.
