Smoke Pushes Deeper Into the Mid West

Smoke from British Columbia conties to cover large portions of both Canada and the US; the image from yesterday. One large continuous plume drops down the mid west all the way through MIssouri, then curves back up and extends from the Great Lakes region through Newfoundland.

A sliver off this plume even moves all the way to the Gulf.

Meanwhile, smoke from California and Oregon is still combining with BC smoke to cover northern California, southern Oregon and Idaho, most of Nevada and Utah, and northwestern Colorado.

Smoke, Smoke, and More Smoke Over North America

The fires burning mainly in British Columbia continue to produce a tremendous amount of extremely dense, relatively high altitude (9-10 km) smoke that stretches the entire west-to-east length of North America:

The Earth Observatory has an item detailing some of the health affects of his smoke:

The fires in California and Oregon are adding to the mix as well. They are also producing smoke that, along with smoke from British Columbia, is being transported out into the Pacific.

Finally, in the upper left of the image you can see smoke from Russian fires moving down through Canada.

Needless to say, it continues to be quite a fire season.

Smoke over North America and Europe

Yesterday's image showed more of the same.

First, smoke from the fires in British Columbia once again cover most of southern Canada and the northern plains of the US:

You can also see smoke from the fires in California and Oregon; this smoke is joining with smoke from BC as it moves out into the Pacific.

Second, smoke from the Canadian fires moved into eastern Europe; meanwhile, another plume was poised off the Atlantic and probably is overhead today:

Finally, smoke from the fires in Russia moved further over Alaska earlier today (note that it's the 17th west of the date line, and the 16th east of the date line):

LP Ozone Profile Version 2.5 Data Release

The OMPS Limb Profiler (LP) Version 2.5 (V2.5) ozone profile data product is now available. This product consists of daily files containing ozone density profiles from separate UV and visible wavelength retrievals. The combined altitude range of these profiles extends from cloud top to 52.5 km, with some overlap in the stratosphere. The ozone daily files also contain cloud detection and altitude information for each measurement over the altitude range 5-35 km. Regular OMPS LP observations began in April 2012, and continue to the present. The data files are available at this location:

LP Aerosol Extinction Coefficient Version 1.0 Data Release

The OMPS Limb Profiler (LP) Version 1.0 (V1.0) aerosol extinction coefficient data product is now available. This product consists of daily files containing aerosol extinction coefficient profiles retrieved at 675 nm (AER675) over the altitude range 10-40 km. The AER675 files also contain cloud detection and altitude information for each measurement over the altitude range 5-35 km. Regular OMPS LP observations began in April 2012, and continue to the present. The data files are available at this location:
