Heavy Smoke Affects AOD in Alaska

The summer months continue to bring fires and surface ozone with them. Ozone AQI reached code red (unhealthy) on Saturday in southern California, and code orange (unhealthy for sensitive groups) in California, Utah, Colorado, and New Mexico (AirNow, top left). Saturday also showed heavy smoke, originating from the Frye Fire in Arizona, traveling northeast into New Mexico (HMS, top right).This image also shows heavy smoke in California, caused by a fire in the Sequoia National forest, heading northeast as well. The HMS image on the bottom left shows a broad area of remnant smoke, mixed with localized medium and heavy smoke on the Alaskan, Yukon Territory border. The smoke this smoke seems to be having a clear effect on AOD, shown by the NASA WorldView image with AOD layer in the bottom left. UMBC Luuft ceilometer shows a homogeneous planetary boundary layer growing strong after 15:00 UTC and reaching heights up to 2000m.
