 ## Objective
 
-Retrieve grib files containing water surface current for the regions between holland and france south west, including east uk coasts.
-Files must be compatible for common opensource navigation tools like (qtvlm, opencpn and xygrib grib visualization tool)
+Provide grib files containing water surface current compatible with the most common navigation tools (opencpn, qtvlm, ...)
 
 ## Data Sources
 
-### copernicus
-probably the most accurate source for european waters.
-- https://data.marine.copernicus.eu/product/IBI_ANALYSISFORECAST_PHY_005_001/services
-### openskiron
-provide interesting grib for several EU regions.
-- https://openskiron.org/en/openwrf
+The data are provided by the IBI-MFC. Thanks to them for their works.
+The data covers the Iberia-Biscay-Ireland region with a resolution of 0.028° and 10 days of forecasts
