Yeah. I don't like the LRAPA.
But in the article you posted this statement appears:
It does not shift it anywhere as much as LRAPA when the numbers are so large as they are now.
All in all the air quality sucks.
Ah that's interesting...that statement about AQandU is part of an edit to the article that happened on 1 September. Last time I read the article was before that. Thanks for pointing this out.
I totally agree, no matter which measure you look at, the air quality around here is awful.

PS. I just realized that on my Mac that if I hold down the control key, the PurpleAir map can tilt and rotate in 3D. No elevation data though.
PPS. My solar production is slowly creeping back up from Wednesday (a.k.a. "nuclear winter day"). It's not back to normal yet but at least it's the right order of magnitude.
