Where is the best real time air quality data? All the sites I see reporting good are obviously wrong at this point. (And: I recognize that this is a minor inconvenience for us on the Peninsula; am thinking of friends and everyone else in the North Bay.)

I use two sites: PurpleAir purpleair.com/map?module=AQI… - closest to realtime (if you choose) - densest network in many areas - lower-quality sensors AQICN aqicn.org/city/california/sa… - probably? higher-quality (more official) sensors, I *think* - better worldwide coverage
