Short summary

Aerosol particles that originate from wildfires can have a large impact on climate by affecting air quality, clouds, precipitation, and Earth's energy budget. We show how fires in the Pacific Northwest ejected mineral dust and smoke high into the troposphere, where they were transported to Colorado, affecting air quality in the Denver metro area. We also demonstrate how specific meteorological conditions were necessary to introduce and additionally clear out the dust and smoke aerosols.
