What drives air quality in Beijing and Delhi
Beijing
Beijing's air quality reflects both urban emissions and regional transport within a broad northern plain setting. Traffic and combustion sources remain important, but citywide episodes often involve secondary particle formation and imported pollution. Under unfavorable meteorology, concentrations can increase rapidly and persist despite local control measures.
Delhi
Delhi is one of the world's most complex urban air-quality environments, shaped by transport emissions, industry, construction dust, and regional sources. Pollution can persist across large areas rather than isolated streets, especially during calm periods. Even short outdoor exposure on poor-air days may represent a meaningful health burden for vulnerable groups.
Both cities are shaped by different combinations of traffic density, terrain, weather patterns, and seasonal events, which is why the same AQI band can feel different on the ground. Checking live readings rather than relying on reputation or past visits is the most reliable way to plan travel, exercise, or outdoor time between the two.
