What the data includes

The dataset for Phan Na contains measurements from two monitoring stations and a total of twelve individual data rows. All six pollutants tracked by the OpenAQ feed are represented: PM1, PM10, PM2.5, relative humidity, temperature and UM003 (particle count). The most recent observations were recorded on 2026‑02‑10 22:00 UTC for five of the variables, showing that the bulk of the data is quite fresh. The exception is PM10, whose latest entry dates back to 2025‑01‑13 23:00 UTC, indicating a gap of more than a year for that particular metric.

Across the twelve rows the recorded values span a fairly wide range. For PM1 the minimum measured concentration is about 17.6 µg/m³ and the maximum reaches roughly 23.8 µg/m³, with a median near 20.7 µg/m³. PM10 varies from 37.8 to 73.5 µg/m³ (median ≈ 55.7 µg/m³), while PM2.5 ranges from zero up to 26.0 µg/m³, the median sitting at about 13.0 µg/m³. Relative humidity values lie between 51.3 % and 56.1 % (median ≈ 53.7 %), temperature runs from 26.6 °C to 31.3 °C (median ≈ 28.9 °C), and UM003 particle counts cover 3,209 to 13,741 particles/cm³ (median ≈ 8,475). The inter‑quartile spreads are modest for most pollutants, suggesting that the typical conditions recorded at the two sites do not fluctuate dramatically within the sampled period.

However, six of the twelve rows are flagged as “unknown” in terms of freshness, and only two rows are classified as recent. This uneven coverage means that while some variables give a current picture of air quality, others—especially PM10—rely on older data points. Consequently, city‑wide conditions may differ from what is captured at these specific stations, and the snapshot should be interpreted with an awareness of both the limited spatial network and the mixed recency of the observations.

Data notes

The current dataset for Phan Na includes five valid measurements and was refreshed Updated within 3 days, with the latest values recorded on 2026‑02‑10T22:00:00+00:00. These figures represent a snapshot of conditions at specific monitoring points; air quality can differ across neighborhoods and change throughout the day, so the displayed values may not reflect conditions everywhere in the city at any given moment.
