In san francisco, pm2 map is wrong

Now in San francisco, the air quality is really bad for the last 3 days.

The air quality station is 159, but on the map, its not red at all and it says 23.

Hello @alan345_33, the PM2.5 layer is a forecast, not a real-time reflection of what is happening. Air quality stations are reporting current values. If there was a sudden event, the forecast is not able to reflect it.
