      @gutiserra This model has a resolution of 7km compared to the ECMWF model with a 13km resolution on windy.com. It should gives shaper forecast images with ICON. As example, just look to wind analyse on Corsica island in Mediterranean Sea with ICON and with ECMWF, you wil see more details with ICON. This is interesting for short forecast time (24h or 48h) close to mountain and sea shore. But more resolution does not mean always better forecast !

                  Yes! I appreciate that!
                  but why you downgraded ECMWF from 9 km to 13 km?

                    Since Mar. 2016 the horizontal grid spacing for ECMWF model is
                    0.1° x 0.1° lat/long.
                    As 1° = 60 Nautical Miles = 111 km
                    0.1° = 11 km

                      according to:
                      https://www.ecmwf.int/en/about/media-centre/news/2016/new-forecast-model-cycle-brings-highest-ever-resolution
                      "... The new cycle reduces the horizontal grid spacing for high-resolution forecasts from 16 km to just 9 km."

                                @dzuremar We are also planning to use ICON data, but Netcdf jar can not open the grib file. What tools or library do you use to handle it?

                                      Is ICON-EU included in the free API?

                                        Just a small comment on model resolution.
                                        In Windy, ICON Europe is presented with a 7km resolution. DWD say it is in fact 6.5km. OK so Windy has rounded its resolution to 7km.
                                        But using the Compare feature the resolution of ICON EU appears to be 6km.

                                        5DB4B9D6-5FA7-4580-B5F6-2FA3D8484F79.jpeg

                                        Same with AROME resolution, the version used by Windy is 1.3km according to Météo France. It is rounded to 2km in Windy.
                                        But in the same table it is shown with the non-rounded resolution.

                                        It would be good to homogenize these values.

                                            Windy should use the correct value everywhere : 6.5km for ICON-EU and 1.3km for AROME
