Generally, the country is covered by clouds and snow covered surfaces, so we're not getting a good view from space of air pollution today. Some agricultural burning in middle of Florida near Okeechobee as seen yesterday. But the winner of the "red dot" award (see AirNow PM loop on the left) is Klamath Falls, Oregon, with peak PM2.5 values near 200 ug/m3. Klamath Falls has had some snow and the area is covered by clouds so we get no view from the top. The Klamath Falls webcam doesn't tell us much about why the air quality is so poor so if you know, post a comment below.
And in Southern California, they are thinking about pasting coriander and black niger seed onto those floats for next Tuesday. If the weather holds like this, it should be a fine Rose Parade.
