Model vs measured
We found no measured PM2.5 sensor cell within 25 km of Shahre Jadide Andisheh, 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 119 µg/m³ in the next 24 hours while NASA satellites detected 3 fire hotspots within 300 km in the last day (nearest about 71 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.
Advice for sensitive groups
At 138, children, older adults, pregnant people and anyone with asthma, COPD or heart disease should limit time outdoors, especially strenuous activity. A well-fitted N95/FFP2 mask cuts particle exposure; it does not filter ozone.
