Air quality in Pallāvaram, estimated
Tamil Nadu, India. No ground monitor we can use is in this city, so these numbers are model estimates, not measurements.
≈38µg/m³
Unhealthy for sensitive groups, estimated
Estimated PM2.5, 7-day average to 2026-09-30, about 2.5× the WHO 24-hour guideline. 30-day average ≈ 31 µg/m³.
Model estimate from the Copernicus Atmosphere Monitoring Service (CAMS), scaled by 1.62 to match 8 measured cities within 300 km over the last week. Adjusted this way, a single day lands within ×1.5 of what a monitor would read about two times in three: a guide, not a measurement. Not ranked on SmogRank's boards.
