@Korina My understanding is that Windy shows forecasts from Copernicus and these other sources are showing both observations from sensors and forecasts. So I guess the question is, why is the forecast consistently off by 300-400%? Maybe this is an issue with the data sourcing.

Windy AQI PM2.5 consistently way lower than other sites and experienced air qualityposted in Bug Reports
Re: Air quality link
I live in Leavenworth WA, and we consistently experience smoke during late summer. Currently, the following sources are showing our air quality for today:
- Windy: 6 µg/m3 - about 25-27 AQI.
- AirNow.gov: 85 AQI (28.2 µg/m3)
- PurpleAir: 83 - 192 AQI (28 to 135 µg/m3)
- IQAir: 94 - 160 AQI (32.5 to 74.8 µg/m3)
This has been a trend for the last month, and often we are experiencing noticeably unhealthy levels (heavy smoke smell, headache, irritated eyes, etc) when Windy says our PM2.5 levels are close to 0. Anyone able to help me understand why Windy is consistently showing much lower levels than experienced or observed on other sites? Thanks.
