Air quality today

The current air‑quality assessment for Pa Tan is classified as USG.

Measurements show that the primary pollutant is PM2.5, with a reported concentration of 48.76 µg/m³ based on five valid observations collected via OpenAQ. This figure reflects the fine‑particle level detected at the time of sampling and does not include any other pollutants. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Pa Tan contains measurements from a single monitoring station that reports six distinct variables: PM1, PM10, PM2.5, relative humidity, temperature and the particle count UM003. In total there are six rows of data – one row per pollutant – all sourced from the same site (โรงเรียนลพบุรีปัญญานุกูล). The most recent observations were recorded on 2026‑02‑10 22:00 UTC for PM1, PM2.5, relative humidity, temperature and UM003, indicating that these five parameters are up‑to‑date within the past week. The PM10 reading is older, last updated on 2025‑01‑13 23:00 UTC, so it reflects conditions from more than a year ago.

Across the pollutants the recorded values show no variation within each series because only a single measurement is present. For PM1 the concentration is 31.168898860613506 µg/m³; for PM2.5 it is 48.7558035680226 µg/m³; and for PM10 it is 65.50297609965007 µg/m³. Relative humidity stands at 55.47083341507684 % and temperature at 25.396428289867586 °C. The particle counter UM003 reports 7,371.752976190477 particles per cubic centimetre.

Because the data set consists of a single station, spatial coverage across Pa Tan is limited; conditions can differ in other neighbourhoods or at different times of day. Most of the pollutants have fresh readings from early February 2026, but the older PM10 value highlights an uneven temporal record. Users should keep in mind that the snapshot reflects only one location and a single point in time for each pollutant.

Data notes

The data shown for Pa Tan reflects five valid measurements and is marked as Updated within 3 days, with the latest values recorded on 2026‑02‑10 at 22:00 UTC. This snapshot provides a current view of ambient air quality but remember conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
