What the data includes
The current station data listed for this city is focused on particulate matter (PM). Only one pollutant, PM2.5, is available from the OpenAQ feed and it comes from three monitoring points in St Peter. All three rows have recent measurements, with the newest reading recorded at 2026-02-10 23:03 UTC, which falls within a three‑day freshness window for every station.
Across the three sites, PM2.5 concentrations range from a low of 3.7 µg/m³ to a high of 12.6 µg/m³, with a median value of 6.1 µg/m³. The 10th percentile sits at about 4.2 µg/m³ and the 90th percentile near 11.3 µg/m³, indicating that most recent observations cluster in the lower half of the overall spread. Because only PM2.5 is reported and the dataset consists of just three recent rows, the picture of air quality in St Peter is limited to these points in time and space; conditions elsewhere in the city or at earlier dates are not captured here.
