What the data includes

The dataset for Mae Chan district contains measurements from twelve rows collected at two monitoring stations. All six pollutants tracked by OpenAQ are present: fine particles (PM1), coarse particles (PM10), fine‑particle mass (PM2.5), relative humidity, temperature and particle count (UM003). The most recent observations were recorded on 2026‑02‑10 22:00 UTC for PM1, PM2.5, relative humidity, temperature and UM003, showing that the bulk of the data is fresh within the last week. Only the PM10 series is older, with its latest entry dated 2025‑01‑09 07:00 UTC, indicating a gap of more than a year for that pollutant.

Across the twelve rows the recorded values span modest ranges. PM1 varies from about 27.12 to 30.49 µg/m³, with a median near 28.80 µg/m³; PM2.5 runs between 42.46 and 47.71 µg/m³, centering on a median of 45.08 µg/m³. Relative humidity fluctuates from roughly 45.88 % to 60.96 %, with a typical value around 53.42 %; temperature is recorded between 22.37 °C and 25.38 °C, medianing at 23.88 °C. The particle‑count metric (UM003) shows counts from about 6 034 to 6 850 particles per cubic centimetre, with a middle value of roughly 6 442.

Because the data come from only two stations, spatial coverage is limited and conditions can differ across the district. The recent timestamps for most pollutants suggest current information is available, yet the outdated PM10 record means that particular metric may not reflect present‑day levels. Users should keep in mind that these figures represent point measurements rather than a comprehensive citywide picture.

Data notes

The data shown are based on five valid measurements and were refreshed recently, having been updated within three days (last update: 2026‑02‑10 22:00 UTC). This snapshot reflects conditions recorded at the time of collection; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in Mae Chan district.
