Air quality today

The air quality in Kaohsiung today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 32.0 µg/m³ and a PM10 concentration of 57.0 µg/m³, based on 72 valid observations. The reported PM2.5 value of 32.0 µg/m³ aligns with the reference level used for the Moderate category, while the PM10 value of 57.0 µg/m³ corresponds to its respective reference. The dataset comprises 72 valid measurement points collected across the monitoring network in the city. No additional pollutants exceed the reporting threshold at this time.

What the data includes

The dataset for Kaohsiung pulls measurements from fifteen monitoring stations, each providing a row for six common air‑quality gases and particles – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm (PM10), particulate matter 2.5 µm (PM2.5) and sulfur dioxide (SO₂). In total there are ninety rows of data. Seventy‑two of those rows have been refreshed within the past thirty days, while eighteen are older than a month; none are marked as unknown or missing. All six pollutants share the same most‑recent timestamp of 2026‑02‑10 23:00 UTC, indicating a coordinated update across the network.

Across the recent records CO values span from 0.19 to 0.57 ppm with a median of 0.36 ppm, while NO₂ ranges between 0.0034 and 0.049 ppm and sits at a median of 0.019 ppm. Ozone shows a broader spread, from 0.001 to 0.061 ppm, median 0.023 ppm. Particulate matter exhibits higher absolute numbers: PM10 varies from 16 to 57 µg/m³ with a median of 43 µg/m³, and PM2.5 runs from 6 to 32 µg/m³, median 25 µg/m³. Sulfur dioxide is the most tightly clustered, ranging only from 0.0003 to 0.0029 ppm with a median of 0.0014 ppm. The median figures sit roughly midway between the observed minima and maxima, suggesting that typical conditions are moderate relative to the extremes captured. Because the data come from a limited set of stations and some rows are older than thirty days, the reported values represent snapshots that can differ across neighbourhoods and over time.
