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 row is available for Cave Junction, and it reports PM2.5 at 4.1 µg/m³ measured at the Cave Junction Forest site, with the most recent timestamp of 2026-02-10 23:00 UTC. This reading falls within a very narrow range—the minimum, median, and maximum values are all identical at 4.1 µg/m³—indicating that there is no observed variability in the dataset for this pollutant.
Because the dataset contains just one row, coverage across pollutants is limited to PM2.5 alone, and there are no additional measurements such as ozone or nitrogen dioxide to compare. The freshness indicator shows the data was updated within the last seven days, which meets a relatively recent reporting standard, but the lack of multiple stations means spatial representation across Cave Junction is minimal. Consequently, while the available figure gives a snapshot of fine particulate concentration at one location and time, broader city‑wide conditions may differ depending on other areas and times not captured by this single entry.
