My government doesn't include PM2.5 in it's weather forecasts and I want to start posting PSAs in city/provincial comms to let people know of poor/unhealthy air quality my government seems to ignore. Ideally this website will be much like breezy and use data fro the Copernicus satellite (which Open Meteo does). I tried searching but all I can find is api's, repositories, and articles on foss weather apps.

Currently Breezy shows AQI is 90 and will be ~120 by midnight, which means if one spends about an hour outside without a k/n95 mask or p100 respirator there can be health consequences. At the same time the governments forecasting shows it's AQI as "3 - Low Risk" for the whole week, which is not true at all. In fact I'm not aware of time when it wasn't 3 lol.
