Indian cities, including Delhi, Mumbai, and Chennai, experience significant air pollution episodes in summer, driven primarily by coarser PM10 particles and ozone, contrasting with winter's PM2.5 dominance. Summer pollution is exacerbated by dust storms (loo and andhi), construction activity, road dust, and vehicular emissions. Ozone forms under strong sunlight from NOx and VOCs, making hotter, sunnier days conducive to its formation. To combat this, cities need to leverage early warning systems for dust storms and air quality, enforce active dust management at construction sites, and reduce NOx and VOC emissions from vehicles and industries. Year-round air quality management plans are crucial, treating both summer and winter pollution with equal seriousness.
- Summer air pollution in Indian cities is characterized by high levels of PM10 and ozone, distinct from the PM2.5 dominance in winter.
- Dust storms, including 'loo' from West Asia and 'andhi' from local thunderstorms, significantly contribute to PM10 spikes.
- Ozone formation is intensified by hot, sunny weather, as it results from the reaction of nitrogen oxides (NOx) and volatile organic compounds (VOCs) under strong sunlight.
