    Air quality (AQI)


    Air quality index (marked as AQI) is developed by Environmental Protection Agency. Values over 300 represents hazardous air quality, between 200-300 very unhealthy, 150-200 unhealthy, 100-150 unhealthy for sensitive groups and below 100 or rather below 50 the air quality is good.

    Data: ICON, DWD (resolution 13 km)
    Updated: 00:00 UTC (next update: 06:00 UTC - prepare)
    Current time: 06:00, 2025/04/21 (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.
