Today, air quality was good and moderate as observed by the AQI animation provided by AirNow. Moderate levels were detected in different region, mostly the Plain Sates, Mississippi Valley and the Carolinas in the Eastern coast (top left). In this last region, HMS detected an area of thin density remnant smoke visible over eastern North Carolina extending into the Atlantic Ocean. This smoke likely originates from the numerous agricultural fires that have occurred over the past several days in the southeastern U.S. (top right). Moreover, thin density remnant smoke from the seasonal fires in Mexico and Central America has moved north towards the southern point of Texas, encompassing the Bay of Campeche and the western Gulf of Mexico. The smoke will likely continue to drift north and eastward along the US coastline throughout the day. All this aerosol activity was captured by MODIS as AOD measurements were high in the aforementioned regions (middle). Finally, OMI reported high NO2 levels over portions of Mid-Atlantic and Great Lakes region (bottom).
