Good AQI; light smoke from numerous fires

Good air quality conditions were experienced today throughout the nation. Moderate PM2.5 levels slowly spread over different stations reaching the highest coverage at about 7PM EDT (top left). HMS indicated that a plume of sulfates was visible off the coast of North Carolina moving southeast and continued to drift offshore until sunset. It is likely that the unknown aerosol is a mixture of remnant smoke originating from the numerous agricultural burns that have been taking place in the Southeast and Southern Plains over the past week (top right). Moreover, bands of blowing dust were visible over much of the Pacific Northwest. Blowing dust from Asia is visible arriving over Northern California, Oregon, and Washington state and continued until sunset. AOD retrievals by MODIS detected high aerosol loadings in the plain states (bottom).
