AOD in the Pacific Northwest and Southwest

Today was a relatively bad day in Air Quality news with heavy concentrations of Aerosol Optical Depth (AOD) on the West Coast. A mixture of elevated PM and Ozone were prevalent along the west coast as concentrated smoke from fires in Northern California, Oregon, Central Washington, Idaho and Western Montana continue to burn. Fires in British Columbia, Ontario and Manitoba have produced heavy smoke mostly dense at the origin with light to moderate concentrations of PM moving south in to the Northern Plain States, the Great Lakes region and much of New England as seen in the HMS image below (top left). Terra satellite imaging below (top right) shows the heavy concentrations of smoke in Oregon and much of Washington throughout the day from those fires in the region. In the Pacific Southwest, ozone reached levels of unhealthy for sensitive groups in what is believed to be the cause of recent air quality events (including smoke), low winds and high temperatures (AirNow bottom left). AOD trajectories (bottom right) show much of the smoke in the Pacific Northwest circulating north and east into the Central and Northern regions of the Rocky Mountain States.
