The Nullschool Earth Visualiser is particularly good at revealing events and patterns.

Current (as of this comment) PM2.5 patterns over the North Pole show major fies in Alaska, Yukon, and Siberia, as well as Greenland.

(Note that not all PM2.5 is combustion or wildfire related -- Sahara dust and hurrican/typhoon/cyclone salt-spray also appear, as do human sources particularly[1] in China and India.)
