Green represents a low level, yellow a moderate level and red a high level. Important: Pollen forecasts from the data source are available only for Europe. No pollen values are displayed outside Europe. Data sources Air quality and pollen data is provided through the Open-Meteo Air Quality API. The underlying air quality data is provided by the Copernicus Atmosphere Monitoring Service (CAMS). In Europe, the European CAMS air quality forecasts are used in particular. Outside Europe, global CAMS air quality data may be available. The displayed values are model-based analysis and forecast data. Data availability, update times and the range of available measurements may vary depending on the location and measurement.
