Air quality today
The air quality today in Nong Han is classified as USG. The primary pollutant identified is PM2.5, with a measured concentration of 35.81 µg/m³ based on five valid observations reported through OpenAQ.
These data reflect the current state of fine particulate matter in the area. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
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 Nong Han contains six measured pollutants – PM1, PM2.5, PM10, relative humidity, temperature and UM003 (particle count). In total there are eleven data rows drawn from two monitoring stations, so each pollutant is not necessarily represented at every location. The most recent observations were all recorded on 2026‑02‑10 22:00 UTC for PM1, PM2.5, relative humidity, temperature and UM003, meaning those five parameters have fresh data that was updated within the last seven days. By contrast, the only PM10 reading comes from an older record dated 2025‑01‑12 02:00 UTC, so information on coarse particulate matter is considerably less current.
Across the recent rows the values show a fairly narrow spread. PM1 ranges from about 23.4 to 24.6 µg/m³ with a median of 24.0 µg/m³; PM2.5 varies between roughly 35.8 and 38.9 µg/m³, median 37.3 µg/m³; temperature moves from 19.0 °C up to 24.0 °C, median 21.5 °C; relative humidity sits between 51.1 % and 55.0 %, median 53.1 %; and UM003 particle counts range from about 1 349 to 4 875 particles/cm³, median around 3 112. These statistics indicate that, for the most recent measurements, conditions are fairly consistent across the limited sampling points.
Because only two stations contribute data, spatial coverage is modest and the older PM10 record highlights a gap in up‑to‑date information for that pollutant. Users should keep in mind that air quality can differ across neighbourhoods and times of day, and the available dataset reflects a snapshot rather than continuous citywide monitoring.

Data notes
The data shown reflects five valid measurements and was updated within 3 days, with the latest reading recorded at 2026‑02‑10T22:00:00+00:00. This snapshot provides a brief view of current conditions; however, air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in Nong Han.
