METCON's smoke forecast reflects the potential impact on air quality from known or satellite-indicated wildfires across the country. The smoke forecast reflects the concentration of smoke particles in the air. Wildfire smoke is in a class of particulates known as PM2.5.  These types of pollutants pose health concerns. 

The wildfire smoke forecast does not consider other air pollutants such as smog, ozone, or particulates emitted from engines or industrial fuel consumption.
