By clicking on the map, a chart showing the changes in hourly ground-level PM10 concentrations over the forecast period in a given location can be viewed.  


The classification of the hourly PM10 concentrations in ambient air follows the one used by the up-to-date air quality data for Europe, where the five categories range from good (< µg/m3) to very poor (> 100 µg/m3). The ambient air quality directives require that to protect human health, daily PM10 concentrations should not exceed 50 µg/m3 more than 35 times per calendar year, and mean annual concentrations should not exceed 40 µg/m3.

In 2021, the World Health Organization (WHO) published new air quality guidelines to protect human health, updating the 2005 air quality guidelines on the basis of a systematic review of the latest scientific evidence of how air pollution damages human health. According to the new WHO guidelines, the mean annual concentration should not exceed 15 µg/m3, and the daily concentration should not exceed 45 µg/m3 more than 3-4 days per year. The European Commission published a proposal for a revision of the Ambient Air Quality Directive in October 2022, which aligns EU air quality standards more closely with 2021 WHO recommendations, and introduces limit values for all air pollutants currently subject to target values, except for ozone. For PM10, daily concentrations should not exceed 45 µg/m3 more than 18 times per calendar year and annual mean concentrations should not exceed 20 µg/m3 by 2030.
