What the data includes
The current station data listed for this city is focused on particulate matter (PM). Only one monitoring row is available for Athens, Tennessee, and it reports a single pollutant: PM2.5 measured in micrograms per cubic meter. The recorded concentration is 16.1 µg/m³, and the same value serves as the minimum, median, and maximum because there is just this one observation. This measurement was last updated on 2026-02-10 23:00 UTC, which falls within a seven‑day freshness window, indicating that the data is relatively recent.
Because the dataset contains only a single station and a solitary pollutant, the coverage is narrow; no other pollutants such as ozone or nitrogen dioxide are represented. The lack of multiple rows means there is no spread of values to describe variability across locations or times within the city. Consequently, while the available figure gives a snapshot of PM2.5 at one point, it does not capture broader spatial or temporal differences that may exist in Athens.
