Out of curiosity - what are typical levels of PM2.5 over there?

I didn't even look at the levels when I came in September because everything looked fine, but lately it's varied a lot, between 100-350 the past few weeks.

130 - 170 AQI is kind of typical. With <50 levels sprinkled throughout the year.

A couple dozen days a year it gets really bad, worse than this current streak.
