@Amar-Drbala Hi, If you purchase a weather station, you will have the option to report its data to Windy, but it will not influence the forecast. The forecast is provided by weather models, and Windy gives you access to several of them for your region. As the ECMWF states “We routinely process data from around 90 satellite instruments as part of our operational daily data assimilation and monitoring activities. We receive 800 million observations daily, and 60 million quality-controlled observations are available daily for use in the Integrated Forecasting System (IFS)” note: IFS is the model run by the ECMWF and shown in Windy. “ the vast majority of these are satellite measurements, but we also benefit from all available observations from non-satellite sources, including surface-based and aircraft reports. … The so-called conventional data nowadays include observations provided by ground stations, radiosondes, sensors on airliners and commercial vessels or installed on anchored or drifting buoys. But these data now represent only about 10% of the total volume because 90% of the data is now provided by satellites”. Furthermore, the weather stations whose data are integrated into the meteorological model assimilation system are official stations such as those certified by the WMO, airport stations, SYNOP stations, etc. Personal stations can be integrated into the MADIS network, but I don't know how the data from these stations is used. Therefore, there is very little chance that you can influence the model forecasts with your weather station.
