What the data includes

The dataset for Khan Pou Senchey pulls from two monitoring stations and contains ten recent rows of observations. All five measured pollutants are represented: PM1, PM2.5, relative humidity, temperature and the particle count UM003. Each variable was last reported on 2026‑02‑10 at 19:00 UTC, which meets the “updated within three days” freshness criterion.

PM1 values range from about 26 µg/m³ to 36 µg/m³, with a median of roughly 31 µg/m³ and the 10th–90th percentile spread (27‑35 µg/m³) indicating modest variability across the recent measurements. PM2.5 shows a broader band, from just over 40 µg/m³ up to 51 µg/m³; the median sits near 46 µg/m³ and the central 80 % of readings lie between 41 and 50 µg/m³. Relative humidity is especially variable, dipping to a low of 0.42 % and climbing to almost 53 %, while the typical value hovers around 27 %. Temperature spans from a cool 2.1 °C up to 28.5 °C, with a median near 15 °C, reflecting both early‑morning and daytime conditions in the recent record. The UM003 particle count exhibits the widest range, from roughly 1,600 particles/cm³ to nearly 9,830 particles/cm³; the median of about 5,700 particles/cm³ sits between the 10th percentile (2,440) and the 90th percentile (9,008), showing considerable fluctuation.

Overall, the data set offers a complete snapshot of five key air‑quality parameters for Khan Pou Senchey, but it is limited to two stations and ten rows. While the timestamps are recent, the modest number of observations means that conditions can still differ across neighborhoods and times not captured in this short window.
