What affects air quality for runners in Mexico City
Mexico City sits in a high-altitude basin where surrounding mountains can limit ventilation and concentrate urban emissions. Traffic remains a major pollution source, but basin meteorology and intense sunlight also drive broad ozone formation. As a result, poor-air episodes can affect wide areas beyond obvious roadside hotspots.
