What the data includes

The current station data listed for this city is focused on particulate matter (PM). Only one monitoring row is available, and it reports PM2.5 concentrations measured at Gorey Pier. The most recent reading was recorded on 2026-02-10 22:51 UTC, which falls within the “updated within 3 days” category, indicating that the data are relatively fresh.

All three statistical summaries for PM2.5—minimum, median and maximum—are identical at 1.48 µg/m³, showing no observed variation in this single record. Because there is just one station reporting, coverage across the city is limited to a single location and does not capture spatial differences that may exist elsewhere on St Martin. Consequently, while the available figure is up‑to‑date, it represents a narrow snapshot rather than a comprehensive view of air quality throughout the island.
