What the data includes

The dataset for Dzongkhag Thromde draws from five monitoring sites and a total of seventy‑five recent observations. All five standard pollutants are represented: PM1, PM2.5, relative humidity, temperature and the particle count UM003. Each pollutant has its own most recent reading, all recorded at the College of Science and Technology on 2026‑02‑10 18:00 UTC.

Across the record the freshest data are from the last three days, but a substantial share is older than three days – thirty‑five rows fall into the “older than three days” bucket and another thirty‑five are classified as unknown in terms of freshness. Consequently, while the latest values give a snapshot of current conditions, many past measurements may not reflect today’s air quality.

The observed ranges show considerable variability. PM1 concentrations span from just over one microgram per cubic metre to more than 117 µg/m³, with a median around 28.6 µg/m³; PM2.5 varies between roughly 5.8 and 192 µg/m³, median 49.7 µg/m³. Relative humidity stays within a narrower band of 37 % to 52 %, centering near 44 %; temperature ranges from about 14.8 °C up to nearly 25 °C, with a typical value close to 22.3 °C. Particle counts (UM003) are the most dispersed, ranging from roughly 323 to 8,748 particles per cubic centimetre, median around 1,889 and a 90th‑percentile near 3,956.

Overall, the data provide a multi‑pollutant picture that is fairly current at the primary site but includes many older or unverified entries. Users should keep in mind that conditions can differ across neighborhoods and over time, especially given the mix of recent and dated observations.
