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 San Na Meng contains six recorded observations from a single monitoring site, identified as “แม่กวง”. All of the standard air‑quality variables are present: PM1, PM10, PM2.5, relative humidity, temperature and the particle count UM003. The most recent measurements were taken on 2026‑02‑10 at 22:00 UTC for five of the six parameters, showing that the bulk of the data is very fresh. Only the PM10 value dates back to 2025‑01‑13 at 23:00 UTC, which makes it considerably older than the rest of the series.
Across the six rows the reported values are identical for each pollutant, indicating a single snapshot rather than a range of readings. The median (and also the minimum and maximum) concentrations are 18.09 µg/m³ for PM1, 28.31 µg/m³ for PM2.5 and 38.60 µg/m³ for PM10. Relative humidity sits at 55.48 % and temperature at 23.87 °C, while the particle counter UM003 records 3 198.56 particles per cubic centimetre. Because each metric shows only one value, there is no observable spread or variability within this dataset.
The coverage is limited to a single location, so conditions elsewhere in San Na Meng may differ from those captured here. The freshness of most parameters suggests the site is being updated regularly, but the older PM10 reading highlights an inconsistency that could affect any analysis relying on that pollutant. Users should keep in mind that these figures represent a momentary snapshot rather than ongoing trends across the city.
