City-vs-City AQI Comparison
LiveCompare any two Indian cities head-to-head on AQI and PM2.5. Live readings plus 9 years of CPCB station history – yearly trends, seasonal heatmaps, worst days, station leaderboards.
214 cities · 551 stations
Open toolSeasonal Pollution Patterns
LiveDrill into the yearly pollution cycle for every CPCB city – monsoon troughs, festival spikes, winter-inversion peaks, and the specific months when each city is most livable.
Open toolAQI Trends Explorer
LiveYear-over-year AQI trajectory for every Indian city with long-run linear regression, best and worst years, COVID-lockdown deltas, and NCAP policy context.
Open toolPollution Health Impact
LiveTranslate India's air-quality data into cigarette-a-day equivalents, life-years lost (EPIC AQLI), and WHO 2021 PM2.5 compliance – for every CPCB city.

Open toolCPCB Monitoring Stations
LiveExplore all 551 CPCB monitoring stations individually – per-station leaderboards, intra-city disparity gaps, and the dirtiest neighbourhoods in each city.
Open toolWHO / EPA / NAQI Benchmark
LiveHow Indian cities measure up to international thresholds. Days exceeding WHO 24-hour PM2.5 guidelines, EPA unhealthy thresholds, and NAQI Poor-or-worse – all on one chart.
Open toolAbout the data
- Source. Central Pollution Control Board (CPCB) station-level daily readings, 2016–2024.
- Coverage. 214 Indian cities, 551 monitoring stations, 605,654 daily readings.
- Live AQI.Open-Meteo CAMS global air-quality model (~45 km resolution) with CPCB station readings on individual city pages.
- Methodology. NAQI for Indian cities, EPA for non-India comparisons. AQI values capped at the 500 scale ceiling; sensor-fault outliers above 500 are excluded.
