Fires and smoke in the Southeast region; More dust in Texas-New Mexico-Oklahoma

Air quality conditions today were mostly good across the nation. Moderate PM2.5 levels were measured in the Great Lakes and Mississippi Valley regions (top left). Hazard mapping system indicated that dust intrusion continue to take place over different states. Three plumes were detected in New Mexico, Texas, and Oklahoma. In addition to the dust episodes numerous fires and small plumes were also detected in Alabama, Georgia and South Carolina (top left). Most of the smoke plumes were of mainly light density and were moving in a northerly direction. Some of the plumes had merged together by the end of the day forming larger patches of thin density smoke. Moreover, areas of thin density smoke from seasonal fires burning in southeastern Mexico and Central America and from flares burning atop rigs in the southern Bay of Campeche were seen across portions of the southwestern Gulf of Mexico. Aerosol Optical Depth (AOD) retrievals by MODIS shows high AOD levels over the mentioned regions where dust and smoke were present (bottom).
