What the data includes
The current station data listed for this city is focused on particulate matter (PM). Only PM2.5 measurements are available, coming from a single monitoring location identified as Berkeley‑Dublin. The most recent reading was recorded on 2026-02-10 23:05 UTC, which falls within the “updated within 7 days” freshness category.
With just one row of data, the reported concentration is consistently 4.54 µg/m³ across the minimum, median, and maximum values, indicating no observed variation at this site during the reporting period. Because there are no additional stations or other pollutants in the dataset, coverage is limited to this single point in time and space, so conditions elsewhere in Dublin may differ. The timestamp’s recency suggests the data is fairly fresh, but the lack of broader spatial or temporal depth means the picture is incomplete for city‑wide assessment.
