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 Nakhon Sawan contains a single monitoring location – the Nakhonsawan Irrigation Project – and reports six common air‑quality pollutants: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀), particulate matter ≤2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). For each pollutant the record shows a single measured value that is also the minimum, median and maximum for the period covered.
Carbon monoxide is reported at 0.88 ppm, nitrogen dioxide at 0.007 ppm, ozone at 0.004 ppm and sulfur dioxide likewise at 0.004 ppm. Particulate matter concentrations are 60.0 µg/m³ for PM₁₀ and 26.2 µg/m³ for PM₂.₅. All values are identical across the statistical percentiles, indicating that only one observation is available for each pollutant.
The timestamps reveal a mixed picture of data freshness. The most recent CO reading dates to 2023‑01‑28 04:00 UTC, NO₂ to 2022‑06‑18 08:00 UTC, O₃ to 2022‑01‑23 00:00 UTC, PM₁₀ to 2023‑03‑31 16:00 UTC and SO₂ to 2023‑02‑16 00:00 UTC. Only the PM₂.₅ measurement is recent, recorded on 2026‑02‑10 21:00 UTC and flagged as updated within the past seven days. Because most observations are several months or years old, the dataset provides a limited snapshot of current conditions; air quality can differ across neighborhoods and over time.
Overall, the city’s data set offers coverage for six key pollutants from one site, but the majority of the readings are dated, with only PM₂.₅ reflecting near‑real‑time information. Users should keep in mind that actual atmospheric conditions may vary beyond what these single, historic values capture.
