A fire up Provo Canyon near Deer Creek Reservoir has burned over 600 acres and, as of this morning, is only 5% contained. Fires up canyons are dangerous to firefighters because canyon winds can change direction and spread the fire rapidly. Read the KSL story
here.
Yesterday I drove up the canyon to measure ozone concentrations. Ozone at the bottom of the canyon was low, in the 40s ppb. Near the fire the ozone concentration was elevated with a max concentration of 64 ppb. Wildfires is one source of ground level ozone (
