What the data includes
The current station data listed for this city is focused on particulate matter (PM). Only one monitoring record is available for Preston, Idaho, and it reports PM2.5 concentrations measured in micrograms per cubic metre. The single entry shows a value of 0.0 µg/m³, with the minimum, median and maximum all recorded as zero, and both the 10th and 90th percentiles also at 0.0 µg/m³.
Because there is just one row of data, coverage across pollutants is limited to this single PM2.5 measurement, and no other contaminants are represented. The most recent reading was taken on 2026-02-11 00:00 UTC, which falls within the last 30 days, indicating that the available data is relatively fresh despite its narrow scope. With only one station contributing, the dataset cannot capture spatial variation across Preston, so conditions may differ in other parts of the city or at times not covered by this solitary measurement.
