Air quality today

The air quality today in Nantou City is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles).

Measurements from six valid monitoring stations show a PM2.5 concentration of 25.0 µg/m³ and a PM10 level of 33.0 µg/m³, as reported by OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Nantou City’s OpenAQ feed currently includes six pollutant measurements from a single monitoring location, giving a snapshot of the city’s air quality at one point in time. The dataset provides values for carbon monoxide (CO) at 0.34 ppm, nitrogen dioxide (NO₂) at 0.012 ppm, ozone (O₃) at 0.006 ppm, particulate matter 10 µg/m³ (PM10) at 33.0 µg/m³, fine particulate matter 2.5 µg/m³ (PM2.5) at 25.0 µg/m³, and sulfur dioxide (SO₂) at 0.0007 ppm. All six pollutants were recorded during the same update on 2026‑02‑10 23:00 UTC, so the freshest timestamp across the board is just under two weeks old.

Because the data come from only one station, there is no variation in the reported values – each pollutant shows a single minimum, median and maximum that are identical (for example, CO’s min, median and max are all 0.34 ppm). This uniformity means the dataset cannot illustrate spatial differences within Nantou City or capture changes over time beyond the most recent reading. The lack of additional rows or older timestamps also indicates that historical trends are unavailable from this source.

In practical terms, users can rely on these six current figures to understand the immediate chemical composition of the air at the monitored site, but they should keep in mind that conditions elsewhere in the city may differ and that no longer‑term data are provided. The dataset’s narrow coverage and single‑time snapshot limit its ability to reflect broader or evolving air quality patterns for Nantou City.
