Air quality today

The air quality in Curtis today is classified as Good. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 2.6 and a PM10 reference value of 2.5, based on eight valid observations collected via OpenAQ.

These figures indicate that the current concentrations are within the range associated with the Good category. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The air‑quality record for Curtis includes data on carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), particulate matter 10 µm or less (PM₁₀) and particulate matter 2.5 µm or less (PM₂.₅). All nine rows in the dataset come from a single monitoring site, identified as TEIXEIRO.

Most of the measurements are very recent: CO, NO₂, PM₁₀ and PM₂.₅ were all last updated on 2026‑02‑09 at 15:00 UTC, which falls into the “updated within 7 days” category. In contrast, the NO reading is older, with its most recent value recorded on 2024‑03‑01 at 00:00 UTC and flagged as old data. This means that for five of the six pollutants the dataset reflects current conditions, while one pollutant relies on information that is nearly two years out of date.

The values themselves are tightly clustered. CO shows a single observed concentration of 170 µg/m³, with the minimum, median and maximum all identical at that level. NO₂ ranges from 4.3 to 7.3 µg/m³, with a median of 5.8 µg/m³; the 10th‑percentile is 4.6 µg/m³ and the 90th‑percentile 7.0 µg/m³. PM₁₀ varies only between 2.3 and 2.5 µg/m³ (median 2.4 µg/m³), while PM₂.₅ spans 2.5 to 2.6 µg/m³ (median 2.55 µg/m³). NO is reported at a single value of 0.22 µg/m³.

Because the dataset draws from just one station, it captures conditions only at that specific location; other parts of Curtis may experience different concentrations, especially for pollutants with limited or outdated coverage such as NO.

Data notes

The current dataset for Curtis includes eight valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑09 at 15:00 UTC, meaning it is updated within three days. This snapshot reflects conditions captured at that time, but air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
