The fires continue to produce dense smoke over the Pacific Northwest. Yesterday CNN reported that " at least 70 large fires were burning across 13 states west of the Mississippi River, according to the National Interagency Coordination Center. California had the most with 13, followed by Nevada with 12 and Idaho with 10, the center said".
Images from MODIS Terra (top, left) show smoke covering Northern California, Oregon, Washington, Idaho, Wyoming, Colorado, Nebraska and Kansas. We can also see the high AOD values associated to all that smoke (top, right). MODIS Aqua shows smoke over the East Coast of the United States (bottom). According to the HMS team, the smoke seen over the East is also due to the Western fires.
Regions with poor air quality correlated with the affected regions aforementioned. Unhealthy levels of ozone (left) and PM2.5 (right) were observed over the Mid-Atlantic and also the Pacific Northwestern.
