Latest sensor values
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
The dataset for Rua Yai contains measurements for six common air‑quality pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM10), particulate matter 2.5 µm or less (PM2.5) and sulphur dioxide (SO₂). All values come from a single monitoring location, the Suphan Buri Provincial Central Stadium, giving a total of six data rows in the current feed.
The timestamps show that most of the records are several years old. CO, NO₂, O₃ and SO₂ were last updated on 2024‑07‑31 or 2024‑07‑30, while PM10 was refreshed on 2025‑05‑10. Only the PM2.5 measurement is relatively recent, having been updated on 2026‑02‑10, which falls within the “updated within 7 days” freshness bucket. Because the data are not uniformly current, they provide only a snapshot of past conditions rather than a real‑time picture of air quality in Rua Yai.
All six pollutants have a single reported value, so the minimum, median and maximum are identical for each. CO is recorded at 0.7 ppm, NO₂ and SO₂ both at 0.001 ppm, O₃ at 0.012 ppm, PM10 at 54.0 µg/m³ and PM2.5 at 36.8 µg/m³. This lack of variation indicates that the dataset does not capture any range or spread for these substances; it simply reflects one measurement per pollutant from the lone station. Consequently, while the data confirm which pollutants are being tracked in Rua Yai, they offer limited insight into how concentrations may change across different locations or times within the city.
