What the data includes

The current station data listed for this city is focused on particulate matter (PM). Only two pollutant entries are present – PM10 and PM2.5 – both coming from a single monitoring site identified as 43N067 – MEMBACH. The dataset contains two rows in total, one for each pollutant, and the most recent update for both was recorded on 2026-02-10 18:00 UTC, which falls within the “updated within 3 days” freshness window.

All reported statistics for PM10 and PM2.5 are zero across the board: the minimum, median, maximum, as well as the 10th and 90th percentiles all read 0.0 µg/m³. Because there is only one station contributing data, the coverage is very limited and does not capture spatial variation across Membach. The timestamps indicate that the information is recent, but the lack of any non‑zero measurements suggests either a period of extremely low particulate concentrations or an issue with data reporting at this location. Consequently, while the data are fresh, they provide only a narrow snapshot of air quality for the city.
