What the data includes

The Cole County air‑quality feed currently includes five measured pollutants from a single monitoring location on Jefferson City Route C. The dataset contains one row for each pollutant, all recorded at the same moment: 2026‑02‑11 00:00 UTC. Because every value was logged on that date, the data are fresh—each measurement is “updated within 7 days” according to the source—but they represent only a snapshot in time rather than an ongoing series.

The available pollutants are PM1 at 2.53 µg/m³, PM2.5 at 3.47 µg/m³, relative humidity at 32.23 %, temperature at 14.42 °C, and particle count (UM003) at 571.41 particles/cm³. For each of these, the minimum, median, and maximum values are identical, indicating that only a single observation exists for the reporting period. This uniformity means there is no spread or variability to describe; the dataset does not capture fluctuations throughout the day or across different days.

With just one sensor feeding all five rows, spatial coverage in Cole County is very limited. The lack of multiple stations means city‑wide conditions could differ from what is recorded at Jefferson City Route C, especially given that local factors such as traffic, industry, and micro‑climate can vary across neighborhoods. While the timestamps are recent, the single‑point nature of the data restricts its ability to reflect broader or longer‑term air‑quality patterns in the county.
