What the data includes
The current station data listed for this city is focused on particulate matter (PM). In Ann Arbor Charter Township the dataset contains a single monitoring row, and the only pollutant reported is PM2.5 measured in micrograms per cubic metre. The reading recorded at the Wastewater Treatment Plant was 27.69 µg/m³, with the same value representing the minimum, median and maximum across the limited sample. This measurement was last updated on 2026-02-10 23:05 UTC, placing it well within the “updated within 7 days” freshness category.
Because there is just one station and only one pollutant type, the coverage is narrow and does not capture spatial variation across the township. The uniform value means there is no observable spread or range beyond the single figure provided. While the timestamp is recent, the paucity of additional rows or pollutants means the snapshot cannot reflect broader temporal trends or differences between neighborhoods. Users should keep in mind that air quality conditions may differ elsewhere and at other times despite this solitary data point.
