Smoke does not respect a forecast zone. It travels a thousand kilometres and lands on a city that had no fire anywhere near it.

What you get
Smoke plume dispersion
Where wildfire smoke goes, at what concentration, over the next five days — including cities far downwind of any fire.
Pollutant forecasting
PM2.5, PM10, ozone and NO₂ with AQI conversion for the local standard, not just the US scale.
Pollen by species
Grass, tree and weed counts separately, because a patient allergic to birch does not care about the composite index.
