- Statement
- Chlorophyll a concentration (Chl) was generated from daily data from ocean colour sensors (i.e. SeaWiFS, MODIS, MERIS, VIIRS) for the years 1998-2017. The algorithms used to derive data from the satellite sensors correspond to the best available algorithms given the optical characteristics of the considered water (i.e. turbid and clear waters). We started from a collection of well-validated operational satellite-based chlorophyll products for the Greater North Sea: 1) CMEMS nr. 67 product where Chl is estimated from the OC5ci algorithm, a combination of OCI (Hu, Lee & Franz, 2012) and OC5 (Gohin, F., et al., 2008.), developed at PML and 2) red-NIR ratio algorithm developed by Gons et al. (2002, 2005) for eutrophic and turbid waters applied to remote sensing reflectance obtained by Envisat-MERIS (MEGS 8.1 processing). For each of these products it was determined for which water types, described in terms remote sensing reflectance (Rrs) spectra, they provided the most accurate chlorophyll estimations based on a variety of reference datasets from the CCRR project (Nechad et al., 2015). These reference data sets were specifically designed to test algorithms and assess their accuracy for retrieving water quality parameters such as Chl concentration. In the next phase of the Chl product generation, a blending process is applied to join chlorophyll-a datasets based on best suited algorithm/water type combination. Quality control has been applied according to the standard satellite product confidence flags for the MEGS8.1 processor, and a specialized flagging approach designed for the OC5ci and Gons algorithms. The original NetCDF file result has been converted into shapefile. The data is then dynamically made available through WFS and statically converted to an INSPIRE-compliant GML file. The INSPIRE EEA 1kmx1km reference grid has been used.
