What the data includes

The current station data listed for this city is focused on particulate matter (PM). Only one monitoring row is available, reporting PM2.5 concentrations measured in micrograms per cubic metre. The single reading shows a value of 8.0 µg/m³ recorded at Glendive on 2026-02-11 00:00 UTC, and the dataset indicates that this measurement was updated within the past seven days.

With just one station contributing data, there is no range of values to compare; the minimum, median, and maximum all equal 8.0 µg/m³, indicating a uniform snapshot rather than a spread of observations. The freshness of the timestamp suggests the information is relatively current, but the limited number of rows means spatial coverage across Dawson County is minimal. Consequently, while the available figure reflects conditions at a specific location and time, broader variations in air quality throughout the county cannot be captured from this dataset alone.
