Most polluted cities in New Mexico, United States
7 measured cities, this year; 4 above the WHO annual guideline. Worst: Anthony at 8.1 µg/m³, #1,769 in the world.
About 59 people in these 3 cities breathed unhealthy air on an average day so far this year.
Ranked by people: each city's population times its share of unhealthy days, those with a daily mean over 35.4 µg/m³ (US AQI 101+). That is how many people living there breathed unhealthy air on an average day. Only cities measured at 2 or more places at least 3 km apart are ranked: one monitor shouldn't speak for a whole city. Population is the city itself, not its wider metro area.
Cities coloured by their PM2.5 over the last 24 hours. Fires, smoke and ash: Oct 5, the newest UTC day mapped.

Estimated: cities without a monitor
New Mexico cities we can't measure, with model estimates for the last 7 days. Listed by population, not ranked: estimates aren't precise enough to rank. Model estimates from the Copernicus Atmosphere Monitoring Service (CAMS), adjusted to measured cities nearby where there are any. Adjusted, a single day lands within ×1.5 of what a monitor would read about two times in three; unadjusted, it can be off by half or double. Treat them as a guide, not a measurement.
| City | 7-day estimate |
|---|---|
| Rio Rancho | ≈ 7 µg/m³ |
| Enchanted Hills | ≈ 6 µg/m³ |
| Santa Fe | ≈ 4 µg/m³ |
| Roswell | ≈ 3 µg/m³ |
| Farmington | ≈ 11 µg/m³ |
| Clovis | ≈ 3 µg/m³ |
| Alamogordo | ≈ 3 µg/m³ |
| Carlsbad | ≈ 4 µg/m³ |
| Gallup | ≈ 4 µg/m³ |
