What the data includes

Christiansburg’s OpenAQ feed draws from a single monitoring site, Craig Mountain, and provides six distinct pollutant measurements. The dataset includes PM1 at 23.64 µg/m³ (last updated 2026‑02‑11 00:00 UTC), PM10 at 10.68 µg/m³ (last updated 2025‑01‑13 23:00 UTC), PM2.5 at 36.62 µg/m³ (last updated 2026‑02‑11 00:00 UTC), relative humidity at 57.43 % (last updated 2026‑02‑11 00:00 UTC), temperature at 14.41 °C (last updated 2026‑02‑11 00:00 UTC) and particle count (UM003) at 3,676.45 particles/cm³ (last updated 2026‑02‑11 00:00 UTC). All six rows are from the same station, so spatial coverage within the city is limited to this single location.

The timestamps show that five of the six measurements were refreshed within the past week, indicating very recent data for most pollutants. PM10, however, is based on a reading from early 2025, making it considerably older than the others and highlighting an uneven update frequency across the dataset. Because each pollutant has only one recorded value (the minimum, median and maximum are identical), there is no observed variability or range over time for any of the parameters at this site.

Overall, Christiansburg’s publicly available air‑quality data offers a snapshot of conditions at Craig Mountain but does not capture citywide variation or recent changes for PM10. Users should keep in mind that the single‑station coverage and the solitary data points mean the figures represent a momentary state rather than a comprehensive picture of ambient air quality across the entire community.
