What affects air quality for runners in Nairobi
Nairobi's air quality varies with traffic density, rapid urban growth, and local topography that affects how pollutants disperse. Busy commuter corridors and industrial areas tend to show the highest concentrations, while greener and less congested zones can remain comparatively cleaner. Daily mobility patterns strongly influence short-term AQI changes.
