SmogRank / South Africa

Air quality in Calcutta, estimated

Mpumalanga, South Africa. No ground monitor we can use is in this city, so these numbers are model estimates, not measurements.

≈10µg/m³
Moderate, estimated

Estimated PM2.5, 7-day average to 2026-09-30, about 0.6× the WHO 24-hour guideline. 30-day average ≈ 11 µg/m³.

Model estimate from the Copernicus Atmosphere Monitoring Service (CAMS). Only 1 measured city is within 300 km, too few to adjust it, so this is the raw model value, which can be off by half or double. Not ranked on SmogRank's boards.
