What the data includes

The dataset for Pai pulls information from 183 measurement rows collected at 32 monitoring stations. All six pollutants tracked by the OpenAQ feed are present: fine particles (PM2.5), coarse particles (PM1 and PM10), relative humidity, temperature, and ultrafine particle count (UM003). The most recent readings for five of the variables were recorded on 2026‑02‑10 22:00 UTC, while the latest PM10 value dates back to 2025‑01‑13 23:00 UTC, indicating that PM10 data are considerably older than the rest. Across the whole set, 141 rows have been updated within the past seven days, 36 are classified as “old,” and six remain of unknown freshness; the remaining entries fall outside these categories.

Typical conditions in Pai can be gauged from the median values: PM2.5 sits at about 20.8 µg/m³, PM1 around 13.2 µg/m³, and PM10 shows a higher median of 36.2 µg/m³, though its maximum reaches 254.8 µg/m³. Relative humidity usually hovers near 55 %, with extremes from 44 % to 82 %. Temperatures are moderate, centering on 18.9 °C and ranging between roughly 15.9 °C and 29.2 °C. The ultrafine particle concentration (UM003) has a median of 2 400 particles/cm³, but values can spike up to 51 100 particles/cm³.

Because the data come from many rows with varying ages, especially for PM10, the snapshot may not capture short‑term fluctuations at every location. Users should keep in mind that conditions can differ across Pai’s neighborhoods and over time, and that some measurements reflect recent observations while others are older.

Data notes

The dataset for Pai includes 141 valid measurements and is Updated within 3 days, with the most recent data recorded at 2026‑02‑10T22:00:00+00:00. These figures represent a snapshot of conditions captured by the monitoring network; actual air quality can differ across neighborhoods and change throughout the day, so values shown may not reflect every location or moment within the city.
