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
Pak Phraek’s OpenAQ feed contains five measured pollutants – nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀), particulate matter ≤2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). All data come from a single monitoring location, the Kanchanaburi Meteorological Station, so the dataset represents one row per pollutant.
The timestamps show that most of the records are several years old. The most recent measurement is for PM₂.₅ at 2026‑02‑10 22:00 UTC, while the newest O₃ reading dates back to 2022‑03‑08 09:00 UTC and the latest NO₂ value was logged on 2022‑08‑31 21:00 UTC. PM₁₀ data were last updated on 2022‑08‑19 16:00 UTC, and SO₂ on 2023‑12‑08 05:00 UTC. Only the PM₂.₅ entry falls within the “updated within 7 days” freshness bucket; the other four pollutants are classified as old data.
The numeric values are all single points with no observed variation across the recorded period. NO₂ and SO₂ each show a constant value of 0.0 ppm, O₃ is consistently 0.1 ppm, PM₁₀ remains at 17.0 µg/m³, and PM₂.₅ is fixed at 33.8 µg/m³. Because there is no spread (minimum, median and maximum are identical), the dataset does not reveal any range or fluctuation for these pollutants.
Overall, the coverage is limited to one station and most of the data are dated, meaning that current air‑quality conditions in Pak Phraek may differ from what is shown here. Users should keep in mind that the available measurements provide a snapshot rather than a continuous picture of local atmospheric composition.
