PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
Mueang Sing Buri’s open‑air quality feed contains six measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), fine particulate matter (PM₂.5), coarse particulate matter (PM₁₀) and sulfur dioxide (SO₂). The data come from three monitoring stations that together provide fifteen recent rows of observations. For CO, NO₂, O₃, PM₂.5 and SO₂ the latest update was recorded on 2026‑02‑10 at 22:00 UTC, while the PM₁₀ reading is older, last refreshed on 2022‑07‑07 at 08:00 UTC.
Across the recent records the observed values show a modest spread. CO ranges from 0.36 to 6.82 ppm with a median of 0.40 ppm; NO₂ stays between 0.000 and 0.020 ppm, median 0.008 ppm; O₃ varies from 0.008 to 0.031 ppm, median 0.010 ppm. PM₂.5 values are higher, spanning 8.0 to 36.2 µg/m³ with a median of 26 µg/m³, while the single PM₁₀ entry sits at 40 µg/m³. SO₂ is low throughout, from 0.001 to 0.002 ppm, median 0.0015 ppm.
The dataset is uneven: five rows are marked “unknown” and another five are older than seven days, meaning that a sizable portion of the city’s air‑quality picture may be missing recent information. Fresh data are available for most gases and fine particles, but the coarse particle measurement (PM₁₀) relies on an outdated entry, so conditions for larger particulates could differ from what is shown. Overall, while the three stations give a snapshot of several key pollutants, the mix of recent and old records suggests that air‑quality can vary across locations and times within Mueang Sing Buri.
