PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The current station data listed for this city is focused on particulate matter (PM). Only a single monitoring location contributes to the dataset, and it reports PM2.5 concentrations measured in micrograms per cubic metre. The lone entry records a concentration of 0.4 µg/m³ at Finley‑S Finley Road, with the most recent timestamp dated 2024-05-30 22:00 UTC. Because this observation falls into the “old” freshness category, it does not represent real‑time conditions.
With just one row of data, the coverage across pollutants is extremely limited; PM2.5 is the only pollutant available for Benton County, Washington. The reported values show no variation—the minimum, median, maximum and both the 10th and 90th percentiles are all identical at 0.4 µg/m³—indicating a single point measurement rather than a range of observations. Consequently, the dataset cannot capture spatial or temporal differences within the city, and any conclusions about current air quality should be drawn with caution, recognizing that conditions may differ elsewhere or have changed since the last recorded reading.
