Air Quality Map

Put this on General Discussion, but thought it would be good here to. Works for North and most of South America, Europe, much of Asia and some places in Africa.

1. Thanks for that...Our air quality is at 440. It's been horrid all day/all week.

2. Minneapolis - air quality 23 -- very good. Very surprising as has been yukky with haze the

last several days, wiping out most of the night sky except for Jupiter and Mars and a half dozen stars. And in the daytime, definitely weakening the sun and making for some interesting sunsets. Today it was overcast, so didn't know how much was the basic weather, and how much was pollution. So am surprised. Just looked outside, it's "clear", I see most of the stars I'm used to seeing, but is definitely "unclear" when I look at any of the horizons up to about 20 degrees above.

4. Why the air quality is great, even tho its grayish brown blotting out stars and dimming the sun --

“Right now, in Minnesota, because the source of the fire is out west, we have good air quality,” said Daniel Dix, a meteorologist with the Minnesota Pollution Control Agency.

The smoke has traveled all the way to East Coast and into the Atlantic Ocean via the jet stream. But, because it’s remained 15,000 to 20,000 feet in the air, it’s not affecting air quality outside of the western United States.

“The Rocky Mountains forced it up so high so it stayed up there,” said Dix. “It was too high in the atmosphere for the atmospheric low level to mix and bring it down.”

Instead, he expects it will stay in the atmosphere, which means it will partially block the sun or make it appear pink. That’s because the smoke filters out the blue and green wavelengths of energy, leaving red, pinks and yellows able to come through.
