Model vs measured
We found no measured PM2.5 sensor cell within 25 km of Datong, so the numbers on this page are model estimates. Models capture regional pollution well but can miss very local sources such as a busy road or a nearby fire.
Wildfire smoke
PM2.5 is forecast to reach 36 µg/m³ in the next 24 hours while NASA satellites detected 12 fire hotspots within 300 km in the last day (nearest about 144 km away). Smoke is a likely contributor: keep windows closed, run an air purifier or HVAC filter, and check the fire map before heading out.
