SmogRank / Portugal

Air quality in Torres Novas, estimated

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

7-day average, estimated≈ 5µg/m³
Estimate, not measuredLikely good

Likely between 3 and 7 µg/m³ (17–39 US AQI): the model's 7-day average to 3 Oct 2026, about 0.3× the WHO 24-hour guideline.

30-day average, estimated: ≈ 4 µg/m³

Model estimate from the Copernicus Atmosphere Monitoring Service (CAMS), scaled by 0.37 to match 7 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.
