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 Khon Kaen City Municipality dataset contains six measured 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 sulfur dioxide (SO₂). All values come from a single monitoring station, so the dataset represents one row per pollutant.
The timestamps show that most of the data are several years old. CO, NO2 and O3 were last recorded on 2022‑04‑09 23:00 UTC, while SO₂ dates back to 2022‑09‑09 08:00 UTC and PM10 to 2023‑03‑21 21:00 UTC. The only pollutant with a recent update is PM2.5, which was refreshed on 2026‑02‑10 22:00 UTC, falling into the “updated within 7 days” freshness category. Because the majority of measurements are old, they may not reflect current conditions in Khon Kaen.
Each pollutant shows a single recorded value with no observed variation across the dataset. CO is reported at 0.26 ppm, NO2 at 0.007 ppm, O3 at 0.001 ppm, PM10 at 93.0 µg/m³, PM2.5 at 32.4 µg/m³ and SO₂ at 0.0 ppm. The lack of a range (minimum, median and maximum are identical) indicates that only one measurement per pollutant is available, limiting insight into daily or seasonal fluctuations.
Overall, the data coverage is narrow – one station supplying six pollutants – and the freshness is uneven, with five out of six parameters dated several years ago. Users should keep in mind that air quality can differ across neighborhoods and over time, so these figures represent a snapshot rather than a comprehensive view of current conditions in Khon Kaen.
