What the data includes
The current station data listed for this city is focused on particulate matter (PM). Only one monitoring location – Cicero Liberty – reports a PM2.5 measurement of 16.5 µg/m³, and that reading was last updated on 2026-02-10 23:00 UTC. Because there is just a single row in the dataset, the available pollutant list consists solely of PM2.5; no other contaminants are represented.
With only one station contributing data, coverage across Cicero is very limited, and the dataset provides essentially a single snapshot rather than a range of values. The reported figure is both the minimum and maximum observed value, as well as the median, indicating no variability within this tiny sample. Freshness is relatively good: the timestamp falls within the past seven days, satisfying the “updated within 7 days” freshness bucket. However, because the dataset lacks additional rows or older entries, it cannot capture spatial or temporal changes that may occur elsewhere in the city.
