      Very nice project,
      I wonder if have you the possibility to collect meteo data from PWS for best local results ??? (like weather underground)

        Thank you for all the hard work on Windyty. It is a very beautiful and accurate forecast site. Although I have looked at the sites and sources listed above, I was unable to find out if there is any data other than satellite data used. Is data being pulled from ground or ocean based stations that go into the modeling as well?

          @ivo Hey, I was trying to use your app here in Norway for snowkiting, and water now in spring/summer. However data used in Windyty is very inaccurate for here, while yr.no seems to be 90% accurate.

          Is there a way to "plug in" data from yr.no without extensive development? Im a product manager for data visualisation app myself so I understand the process and depth, but dont know your code well to undestand this.

            @DaveySoCal Yes, the weather models use observed sources that are available at the time of ingest. Common ingest sources are RADAR, satellite, aircraft reports, upper air soundings (weather balloons), ground stations, and ocean buoys. You can read more about the ingest data sources for the GFS here (it is the same for the other models), http://www.emc.ncep.noaa.gov/GFS/doc.php paragraph 1.3 (GDAS).

              Hello and thanks for this incredible website.

              My question is: Where do you get the METARs and TAFs data for the airports from? Is it an official source?

              Thank you very much for all your hard work on this project. Regards!!!

                  Maybe interesting for the windy team, there are now most data of Dwd opendata http://www.dwd.de/EN/ourservices/opendata/opendata.html

                  Maybe you can make windy better with this

                      Hello,

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

                                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?
