In WeatherPro there are several types of data: observational and forecast data, as well as radar and satellite images.
As a MeteoGroup product we primarily use our own multi-model approach (MOS) for the forecasts in WeatherPro. Our approach is mostly based on data from the leading global weather models, e.g. ECMWF (European Centre for Medium-Range Weather Forecasts) and other local models like the American GFS (Global Forecast System) and the British UKMO (UK Met Office). The forecast data is updated at several, undetermined times each day.
The observational data offered in WeatherPro comes from our own private weather measurement network, comprising of approximately 1,300 stations from around the world and national weather services (whose data is supplied by the official World Meteorological Organisation (WMO) weather stations worldwide).
We would like to be able to offer updated data at more regular intervals, but the WMO weather stations only provide once hourly data (only weather stations at airports refresh their data every 20 minutes). Radar images from the national weather services are updated every 15 minutes, and satellite images are received from the geostationary satellites at intervals of between 15 minutes and 3 hours.
