DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1630Z UTC August 7, 2007
Eastern US: A large area of moderate haze with embedded smoke from ID/MT fires can be seen along the eastern side of a large upperlevel anticyclone centered over E TN; the smoke is moving due south in the mid to upper levels under this influence. The smoke is mainly mid to upper level while pollution/ozone haze is the surface contribution. Sfc flow would transport the haze toward the NE east of the Appalachians. The haze smoke covers all of PA, WV, MD, DE, NJ, VA, NC, SC, GA, AL, FL, Long Island NY and over adjacent coastal waters including the Northern Bahamian islands. The smoke over the ocean is bound by the US coastline from Miami to the southern coast New England to 41N69W then south to 39N69W to 36N72W to 30N75W to 25N77W to Miami. This area is on average about 350km offshore with a maximum distance around 600 km from Savanna, GA eastward and minimum distance of 200km from Cape Hatteras, NC southeastward. Michigan: The Sleeper Lake fire is producing a moderate to dense plume of smoke that extends due north to around 47N over E Lake Superior. The plume is about 20km wide. Norther US Rockies, S Canadian Great Plains, N US Great Plains: An area of dense smoke from MT, ID fires is shaped in an arch around 300km wide centered on a line between the Salmon River Mtns in Central ID to Great Falls, MT to Killdeer,SK (near US/Canada line) with the apex (and northern boundary) near Lake Diefenbaker and then continues SE to the MT/ND/SK boundary to Fargo,ND. A small pocket of moderately dense smoke can be seen over and just east of the Big Horn mountain range across N WY, S MT moving due east. Gallina
