Latest sensor values
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 one pollutant – PM2.5 – is reported from a single monitoring location, Clarkston‑13th St, giving a snapshot of fine particle concentration in the area. The dataset contains just one row, so coverage across the city is limited to that specific site.
The most recent measurement was recorded on 2026-02-10 23:00 UTC, which places it well within the past week and therefore reflects fairly current conditions. All reported statistics for PM2.5 – minimum, median, maximum, as well as the 10th and 90th percentiles – are identical at 6.0 µg/m³, indicating no observed variation in this limited sample. Because only one station contributes data, any spatial differences in air quality across Clarkston cannot be captured here, and the uniform value should not be taken as representative of the entire city’s atmosphere.
