Global Air Pollution (image) European Commission Joint Research Centre Share Print E-Mail Caption Scientists simulated the level of small particle pollutants (PM2.5) in microgrammes per cubic metre. The atlas at the top shows the current-day average pollutant concentration for the whole year and the image at the bottom shows the average for the month with the highest concentration of pollutant at each grid point. In regions likely to become prone to wildfires, air pollution could reach dangerous levels during fire season.
