Smoke from fires in the Washington, Oregon, Idaho, and California was
transported into Utah starting August 15th and didn't clear out for over a week. The red dots in the image below show the location of fires based on MODIS observations on August 20th. These fires include the largest fire in Washington's history.
Air quality across Utah was impacted by the smoke. At MtMet between the 18th and 22nd PM 2.5 concentrations were in the moderate range and unhealthy for sensitive groups range.
Also shown is the ozone at MtMet during the same time. Other observations at MtMet are
here.
University of Utah trucks, KSL Chopper, and TRAX drove around measuring ozone on August 19th. All observations available
here.
Looking towards valley from near Bountiful Peak. Lidar observations on August 20th. On the day with the highest backscatter you can see the upper levels winds from the northwest were relatively strong.

On the bright side, we I enjoyed the orange sunsets!
