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 Phetchabun pulls in 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). Across the city there are seven data rows coming from two monitoring stations, with all values recorded at the same recent timestamp of 2026‑02‑10 22:00 UTC, which falls within the “updated within 7 days” freshness window.
PM₂.₅ is the only pollutant with more than one observation (two rows). Its measurements span from a low of 5.0 µg/m³ to a high of 26.3 µg/m³, with a median value of 15.65 µg/m³ and an inter‑percentile range that puts the 10th percentile at about 7.1 µg/m³ and the 90th percentile near 24.2 µg/m³. All other pollutants have a single reported figure: CO is consistently 0.4 ppm, NO₂ stays at 0.007 ppm, O₃ at 0.018 ppm, PM₁₀ at 40.0 µg/m³ and SO₂ at 0.002 ppm. Because each of these appears only once, the dataset cannot show any spread or variability for them.
The overall coverage is modest: while the two stations together provide a complete set of six pollutants, most of those pollutants are represented by just one row, limiting insight into spatial differences across the city. The data’s freshness is strong – every measurement was logged on 2026‑02‑10, well within the past week – but the limited number of observations means that conditions can still vary by location and time beyond what is captured here.
