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 Ko Khwang contains measurements from a single monitoring site that reported six separate pollutant readings on the most recent update of 2026‑02‑10 22:00 UTC. All six 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)—are represented, each with a single recorded value that also serves as the minimum, median and maximum for that day.
Because there is only one station contributing data, the coverage across the city is limited to the location of the Chanthaburi Meteorological Station. The timestamps are uniformly recent; every pollutant’s last‑updated time falls within the same 7‑day freshness window, indicating that the information reflects conditions as of early February rather than older or unknown periods.
The numeric values show no internal spread: CO is recorded at 0.2 ppm, NO₂ at 0.007 ppm, O₃ at 0.022 ppm, PM10 at 58.0 µg/m³, PM2.5 at 28.5 µg/m³ and SO₂ at 0.002 ppm. This uniformity means the dataset provides a single snapshot rather than a range of observations over time, so any variation in air quality across different parts of Ko Khwang or over longer periods is not captured here. Users should keep in mind that conditions can differ by location and moment, and the current data reflects only what was measured at one site on one recent date.
