Why is the AQI so high?

Anonymous
My app has been showing air quality (due to PM2.5) hovering around 100 for the past several days. Any idea why? Wanted to run outside but I’m sensitive.

The fog is trapping pollution.

I didn’t know that was a thing! Does that also mean that when the fog lifts (presumably later this morning) the air quality might improve?

Yes. It’s better today you’ll notice.

It is the weather. The pattern was quite stagnant this week and it just traps the pollutants. As PP noted it is already better today and should be ok into next week.
