It looks like smoke will continue to plague the continent for a few more days.

Lots of Smoke Transport from North Amereica To Europe

This animation of the last ten days shows:

1) The fires from western Canada and the US were still producing large amounts of smoke, covering large sections of both countries, and

2) A lot of that smoke was transported across to Europe.

Smoke Over North America, 20 Aug 2018

The smoke has been so prevalent and long-lasting that I've run out of inventive and nifty titles for these blog items, so I'm resorting to dull titles with dates.

Much of the smoke is low enough in the atmosphere to affect air quality in much of the west, all along the Front Range of the Rockies, and into the midwest. Unhealthy air advisories have been issued for the northwest:

And milky skies are evident as far east as Maine:

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:
