PM in the Pacific Southwest

Today was a good day in Air Quality news with very low to moderately dense PM observed throughout the nation (AirNow, top left). Fires in Southern California produced moderately dense smoke that has traveled Southwest into the Pacific Ocean while PM concentrations were most dense at the origin. It is believed that fires in the Northern Plain States and Western Great Lakes regions of the nation may have contributed to the elevated PM in the Mid-Atlantic and Northeast region of the States (HMS, top right). AOD trajectories shows aerosols from the Pacific Northwest and possibly fires in Mexico moving east towards the Mid-Atlantic and Northeast regions of the nation for the course of 48 hours (VIIRS CONUS, bottom).
