Air quality in Eritrea

No monitor here publishes data we're allowed to use, so Eritrea has no measured ranking yet. Model estimates below.

Estimated: cities without a monitor

Eritrea 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	Band
Asmara	≈ 16 µg/m³	Low risk
Keren	≈ 15 µg/m³	Low risk
Himora	≈ 17 µg/m³	Low risk
Af’abet	≈ 17 µg/m³	Low risk
Massawa	≈ 23 µg/m³	Low risk
Assab	≈ 19 µg/m³	Low risk
Mendefera	≈ 15 µg/m³	Low risk
Barentu	≈ 16 µg/m³	Low risk
