          @Tomber42 Hi, how do I get spatial data from Dwd?

            Hello,

            I was wondering if you could incorporate the modeling information for Canada. Data found here:

              Please add ICON and AROME boundaries
              in the map with the "brief overview of all models..."

                      AROME is provided with 2 resolutions 1.25km and 2.5km. One of them is updated faster. I suppose that Windy use only the 2.5km version? In this case it should better, may be, to mention only the resolution used on Windy ?
                      For GFS you give now a 13km resolution. I have understood that this 13km resolution is used for computation, but then data are dispachted with a 22/23km resolution. Or has this been changed

                        @idefix37 Hello ! We use AROME with resolution 0.01° (1.3km). Both of the AROME resolutions have 00, 06, 12 and 18 ref time runs. There are also 03, 09, 15 and 21 ref time runs which we don't process. Advantage of AROME 0.025° (2.5km) is that it includes pressure-level layers. AROME 0.01° provides only surface-level layers, only wind and relative humidity are additionally in 20m, 50m and 100m altitude. However, AROME 0.025° also covers much smaller area - a square that covers whole France and a bit of surrounding area.

                          Hi @ivo! I am also curious about this topic. As I understand ECMWF is the model weather files/forecast is modeled in, and forecasts are produced of several met offices use in Europe. For what I know Yr.no (Norwegian Met Office) has more detailed topography, we often find their forecasts to be more accurate than i.e British Met Office.

                          Is this correctly understood? In case, is the yr.no data included in windy.com?

                            @andreasroe Do they offer their data for free?

                              They offer (for free) very little data and only for limited areas.

                                How can I see the source of data windy is using, for example regarding weather radar?

                                  For the source of forecast data (model), press the "clock" symbol

                                    Lightning data come from blitzortung.
                                    WX radar data from national meteo. services, shown if you zoom in a country
                                    e.g. DWD for Germany

                                      For the ECMWF forecast data do you guys use the paid subscription or is there any free/community plan available for independent researchers ?

                                        Any plans to add ARPEGE model which better covers Mediterranean Sea.

                                        It seems that GRIB files should be free, similar to AROME that is already supported in Windy.

                                          Model data from the Norwegian Meteorological Institute which is also used for Yr.no in Scandinavia is freely available at http://thredds.met.no

                                            I Sail in the Florida Keys. For today short term for case American GFS 22km resolution much different than Europe ECMWF 9km model. For instance rain arrival is different by 6 hours! Also don’t agree on the amount of precipitation.Anyone else thinks This is strange?!
