Air quality today

The air quality in Hsinchu is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 16.0 µg/m³ and a PM10 level of 26.0 µg/m³, based on six valid observations reported through OpenAQ.

These values reflect the present state of ambient air in the city without implying any health implications. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Hsinchu air‑quality feed includes six measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM10), particulate matter ≤2.5 µm (PM2.5) and sulfur dioxide (SO₂). Data come from 13 recent rows collected at three monitoring stations, each row representing a separate measurement event. All pollutants have been updated within the past seven days, with the most recent timestamp recorded on 2026‑02‑10 at 23:00 UTC for every compound.

Across the dataset the observed values show modest variation. PM2.5 ranges from a low of 7.41 µg/m³ to a high of 16.0 µg/m³, with a median of 8.0 µg/m³; CO spans 0.17‑0.39 ppm (median 0.28 ppm); NO₂ varies between 0.0053 and 0.028 ppm (median 0.0167 ppm); O₃ is recorded from 0.001 to 0.0383 ppm (median 0.0196 ppm); PM10 runs from 22.0 to 26.0 µg/m³ (median 24.0 µg/m³); and SO₂ lies between 0.0018 and 0.0023 ppm (median 0.00205 ppm). The 10th‑percentile values are close to the minima for each pollutant, while the 90th‑percentile values approach the maxima, indicating a relatively tight spread around typical levels.

Although the data set is current, coverage is uneven: three stations provide all six pollutants, yet only 13 rows are classified as recent and one row remains of unknown freshness. Consequently, while the snapshot reflects conditions at the time of measurement, it does not capture finer spatial or temporal fluctuations that may occur elsewhere in the city.

Data notes

The dataset for Hsinchu includes six valid measurements and is updated within three days, with the most recent values recorded at 2026‑02‑10T23:00:00+00:00. These figures represent a snapshot of ambient conditions across the city; actual air quality can differ by specific location and time of day, so users should consider local variations when interpreting the data.
