What the data includes

The air‑quality record for Mueang Nakhon Nayok District comes from a single monitoring site operated by the Nakhon Nayok Municipality Public Health Service Center, so there is one row of data for each pollutant. All five measured species – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), fine particulate matter (PM2.5) and sulfur dioxide (SO₂) – have recent observations; the latest timestamp for every parameter is 2026‑02‑10 22:00 UTC, which falls within the past seven days. Because each pollutant has only one reported value, the minimum, median and maximum are identical, giving a clear picture of the current snapshot but no indication of variability over time.

The CO concentration stands at 0.3 ppm, NO₂ at 0.014 ppm, O₃ at 0.03 ppm, PM2.5 at 16.4 µg/m³ and SO₂ at 0.001 ppm. With a single measurement per pollutant, the data set does not reveal any spread; the reported percentiles (10th and 90th) match the exact value for each species. This uniformity means that while the figures are up‑to‑date, they cannot describe fluctuations that might occur across different parts of the district or over shorter intervals.

Because the coverage relies on one monitoring location, spatial representation is limited. Conditions can differ in other neighborhoods, especially where traffic density, industrial activity or vegetation vary. The freshness of the data – all entries updated within the last week – ensures that the numbers reflect the most recent conditions captured at this site, but users should keep in mind that a broader network would be needed to capture city‑wide patterns and day‑to‑day changes.
