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 Cass Lake, and it reports a single pollutant: PM2.5 measured in micrograms per cubic metre. The recorded value is 3.6 µg/m³, which is also the minimum, median and maximum observed across that station’s recent readings.
All of the data for this location are relatively fresh, with the most recent timestamp logged on 2026-02-10 23:00 UTC and flagged as updated within the past seven days. Because there is just one row and a single pollutant, the dataset does not provide a broader spatial or temporal spread; the range of values is effectively a single point rather than a distribution. Consequently, while the figure gives an immediate snapshot of particulate levels at that specific site, it cannot capture variations that might occur elsewhere in Cass Lake or over longer periods.
