DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1530Z SEPTEMBER 1, 2008

Nation's Midsection:
A large of of light to moderately dense aerosol covered much of the
central US. This is likely a mix of remnant smoke and sulfur dioxide
(SO2) from Alaskan volcanic eruptions a few weeks ago. The western extent
of the light aerosol is from Texas north into eastern North Dakota. The
aerosol is moderately dense over portions of western Kentucky, southern
Indiana, Illinois, Missouri, Iowa, western Wisconsin and Minnesota. The
area also extends into western Ontario.

Pacific Northwest:
An area of thin aerosol was seen moving eastward across eastern Oregon,
eastern Washington and into Idaho. The origin is unknown but possibly
remnant SO2 from the Alaskan volcanoes.

Central Canada:
An area of possible SO2 was seen extending from northeast Manitoba across
central and northern Hudson Bay.

Unless otherwise indicated:

Areas of smoke are analyzed using GOES-EAST and GOES-WEST Visible satellite imagery.

Only a general description of areas of smoke or significant smoke plumes will be analyzed.

A quantitative assessment of the density/amount of particulate or the vertical distribution is not included.

Widespread cloudiness may prevent the detection of smoke even from significant fires.
