Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
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 St Mary, and it reports a single pollutant: PM2.5 measured in micrograms per cubic metre. The reading from the St Mary's Village site shows a value of 12.76 µg/m³, with the minimum, median and maximum all identical at 12.76 µg/m³, indicating that this is the sole observation captured for the period.
The dataset is very recent; the latest timestamp is 2026-02-10 23:00 UTC, which falls within the three‑day freshness window noted in the source metadata. Because there is just a single station and a single pollutant, coverage across St Mary is limited to that location and cannot represent variation elsewhere on the island. The uniform value also means there is no observed spread or range for PM2.5 at this time, so any spatial or temporal differences in particulate levels remain undocumented until additional stations or measurements become available.
