What the data includes

The dataset for Denton pulls information from 26 recorded rows across 4 monitoring stations and covers seven measured pollutants: ozone (O₃), PM1, PM2.5, PM10, relative humidity, temperature and particle count (UM003). The most recent measurements are from early February 2026; the newest timestamp overall is 2026‑02‑11 00:00 UTC for PM2.5, PM1, relative humidity, temperature, UM003 and O₃ (the latter at 2026‑02‑10 23:00 UTC). For PM10 the latest entry is older, from 2025‑01‑13 23:00 UTC.

Out of the 26 rows, seven have been updated within the last seven days, another seven are classified as “old” and twelve lack a clear freshness label. This mix means that while some recent data points exist, a substantial portion of the record is dated or uncertain, so conditions can differ across locations and times in Denton.

The pollutant values show modest ranges. PM2.5 median concentration sits at 4.52 µg/m³ with a minimum of 0.0 and a maximum near 7.58 µg/m³; the 10th‑percentile is zero while the 90th‑percentile reaches 7.35 µg/m³, indicating most recent readings cluster toward the lower end but can spike higher. PM1 median is 1.67 µg/m³ (range 0.05–5.03 µg/m³) and PM10 median 2.90 µg/m³ (range 0.25–7.81 µg/m³). Relative humidity varies from about 30.5 % to 54.3 %, with a median of 41.5 %; temperature spans 19.1 °C to 34.4 °C, median 27.2 °C. Particle count (UM003) shows a broad spread, median 648 particles/cm³, minimum 155 and maximum 988 particles/cm³. Ozone is reported as a single constant value of 0.025 ppm from the Denton Airport South site.

Overall, the data provides a snapshot of air‑quality related metrics for Denton but reflects uneven temporal coverage across pollutants and stations, so users should consider that conditions may vary locally and over time.
