What the data includes

The dataset for Mailiao Township includes six measured air‑quality variables – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or smaller (PM₁₀), fine particulate matter 2.5 µm or smaller (PM₂.₅) and sulfur dioxide (SO₂). All six pollutants are represented by a single monitoring record, so the station coverage for this location consists of one row per pollutant.

Each measurement was last updated on 2026‑02‑10 at 23:00 UTC, which falls within the “updated within 7 days” freshness category. Because there is only one observation per pollutant, the reported minimum, median and maximum values are identical. CO registers at 0.41 ppm, NO₂ at 0.018 ppm, O₃ at 0.001 ppm, PM₁₀ at 77.0 µg/m³, PM₂.₅ at 55.0 µg/m³ and SO₂ at 0.0013 ppm. The percentile‑10 and percentile‑90 figures match these same numbers, indicating no observed variability in the current snapshot.

With just one recent data point for each pollutant, the dataset provides a very narrow view of air quality in Mailiao Township. While the timestamps are fresh, the lack of multiple rows means there is no information on short‑term fluctuations or spatial differences across the township. Consequently, any single reading should be understood as a momentary snapshot rather than a comprehensive picture of conditions that can change over time and location.
