Air quality today

The air quality in Chaozhou is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 22.0 µg/m³ and a PM10 level of 42.0 µg/m³, based on six valid observations reported through OpenAQ.

These figures reflect the present conditions without implying any trend or cause. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Chaozhou contains a single monitoring station that reports six common air‑quality 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). All measurements come from the same site in Pingtung County – Chaozhou, and each pollutant has exactly one recorded value for the most recent update on 2026‑02‑10 at 23:00 UTC.

Across the six pollutants the reported concentrations are identical to their minimum, median and maximum values, indicating no observed variation within the dataset. CO is measured at 0.29 ppm, NO2 at 0.007 ppm, O3 at 0.015 ppm, PM10 at 42.0 µg/m³, PM2.5 at 22.0 µg/m³ and SO2 at 0.0013 ppm. Because there is only one row per pollutant, the inter‑quartile range (p10 to p90) collapses to a single point for each.

The freshness of the data is uniform: every pollutant’s last‑updated timestamp falls within the “within 7 days” freshness bucket, with no older or unknown entries. However, the dataset’s breadth is limited – only one station contributes all six measurements, so spatial coverage across Chaozhou is minimal and cannot capture local variations that might exist elsewhere in the city. Consequently, while the numbers are current, they represent a snapshot from a single location rather than a comprehensive view of air quality throughout the entire urban area.

Data notes

The current dataset for Chaozhou includes six valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 23:00 UTC; it is therefore considered updated within three days. While this snapshot reflects overall conditions across the city, air quality can differ by specific location and time of day, so individual experiences may vary.
