This directory lists the city pages that include written local context beyond raw AQI feeds. Each guide combines live station data with original notes about seasonal patterns, common pollution sources, and practical actions.

We only surface pages here once they have enough city-specific analysis to stand on their own.
City Guide
Delhi experiences some of the sharpest AQI swings in India because the city is landlocked and ringed by industrial clusters. Winter stubble burning in neighbouring states, heavy traffic, and calm winds combine to trap fine particulate matter over the capital.

Mumbai benefits from the Arabian Sea breeze but still battles vehicular exhaust, port activity, and construction dust. Humidity often keeps pollutants lingering over low-lying suburbs.

Bangalore's elevated terrain moderates pollution compared with other metros, yet rapid growth has intensified traffic emissions and construction dust, particularly in emerging tech corridors.

Chennai's coastline brings welcome ventilation, yet petroleum refining, port operations, and dense traffic leave neighbourhoods with fluctuating air quality through the year.

Kolkata experiences a mix of old vehicle exhaust, coal-based industry along the Hooghly, and high humidity that traps pollutants, especially during winter inversions.

Hyderabad has seen rapid construction and expanding highways, increasing particulate loads alongside a growing ozone challenge during hot, still afternoons.

Pune's valley topography and automotive manufacturing belt create localised pollution pockets. The neighbouring Pimpri-Chinchwad industrial zone adds to the particulate load.

Ahmedabad combines industrial estates, heavy traffic, and arid climate. Dust from construction and surrounding drylands frequently elevates PM10.

Lucknow's dense core, mixed fuel usage, and nearby agricultural burning contribute to persistent winter smog. Narrow lanes can trap emissions longer than open boulevards.

Jaipur blends desert dust with tourism-driven traffic and burgeoning construction. Stone cutting and polishing units contribute to coarse particulate loads.
Open Jaipur guideCity Guide
Patna faces consistently high particulate levels because of dense traffic, biomass burning, and numerous brick kilns ringing the city. Limited wind movement allows pollution to linger overnight.

Chandigarh benefits from planned green sectors, yet vehicular growth and seasonal smoke from neighbouring states influence its AQI.
