   #MSP AQI now at 29, was as low as 15 this morning. Unbelievable!

   For reference, we were well over 250 and heading for 300 at the worst of the smoke. I don’t know whether AQI scales linearly, and thus whether “16x lower” is meaningful in this context, but…well, I do know this is cause for celebration!
