What the data includes

The OpenAQ feed for Khok Sung includes data on carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), sulfur dioxide (SO₂), fine particulate matter (PM₂.5), coarse particles (PM₁₀) and ultrafine particles (PM₁), as well as relative humidity. The dataset comprises twelve individual rows drawn from three monitoring stations, giving a modest spatial snapshot of the city’s air quality.

For most gases the latest measurements were recorded on 2026‑02‑10 22:00 UTC, showing CO at 1.1 ppm, NO₂ at 0.009 ppm, O₃ at 0.016 ppm and SO₂ at 0.001 ppm, all from the Mueang Chaiyaphum Municipality Stadium sensor. PM₂.5 values range from a minimum of 10.26 µg/m³ to a maximum of 26.6 µg/m³, with a median of 16.8 µg/m³ and the 90th percentile at 24.64 µg/m³, also reported on 2026‑02‑10. In contrast, PM₁, PM₁₀ and relative humidity come from an older record dated 2024‑06‑26 04:00 UTC at the โรงเรียนโสตศึกษาจังหวัดชัยภูมิ site, showing PM₁ at about 6.94 µg/m³, PM₁₀ at roughly 10.44 µg/m³ and humidity near 60.4 %. These three variables therefore reflect conditions from more than a year ago, while the gas‑phase pollutants are current.

Overall the data set presents a mixed picture of freshness: half of the monitored parameters have updates within the past week, but the particle size fractions and humidity are based on legacy readings. The spread in PM₂.5 values indicates noticeable variability across the limited sampling points, whereas the gaseous pollutants show uniform single‑value entries for the most recent timestamp. Because only three stations contribute, conditions can differ by location and time, and the older rows mean that a full, up‑to‑date view of particulate matter and humidity is not currently available.
