Here you can read about our data sources. Ventusky serves as a platform for visualizing meteorological data. The main provider of meteorological data for Ventusky is DWD and NOAA. However, the radar layers (marked as EURAD, USRAD and WORAD) have several other country-specific providers, which are summarized below.

Data: HRRR, NOAA (resolution 3 km)
Updated: 04:00 UTC (next update: 05:00 UTC - prepare)
Current time: 06:00, 2025/03/30 (UTC)
For this output data, temperature is shown for 2 m above ground. The calculations take into account the terrain (elevation), but with lower resolution than in reality. Therefore the models cannot differentiate, for instance, the temperature on a mountain peak or on a city square scorched by the sun. The general rule is that the centres of large cities are 1 °C to 3 °C warmer than the surrounding area or natural landscapes. Significant temperature differences over a small area are primarily caused in the winter by an inversion. A short yet noticeable cooling can also occur after a local summer storm.
