What the data includes

The OpenAQ feed for Weilheim i.OB contains data from a single monitoring location, so all values represent one point in the city rather than a network of stations. Six different parameters are reported: PM1, PM10, PM2.5, relative humidity, temperature and particle count (UM003). The most recent measurements were taken on 2026‑02‑10 at 19:00 UTC for five of the pollutants, showing that the data set is fairly fresh for those variables. Only the PM10 reading is older, last updated on 2025‑01‑13 at 23:00 UTC, which means that information on coarse particles is more than a year out of date.

Across the six parameters the recorded values are all single‑point observations with no variation in the data set: each pollutant has identical minimum, median and maximum figures. PM1 registers 24.34 µg/m³, PM2.5 37.64 µg/m³ and PM10 54.05 µg/m³. Relative humidity is 44.91 % and temperature 10.73 °C at the time of measurement. The particle counter (UM003) reports 3 907.22 particles per cubic centimetre. Because there is only one row per pollutant, the spread (p10‑p90) is effectively zero, indicating no recorded range for any parameter.

The data therefore give a snapshot rather than a trend: freshness is good for most variables but limited to a single location and a single moment, and the older PM10 value highlights uneven temporal coverage across pollutants. Users should keep in mind that air quality can differ across neighborhoods and over time, so this point‑source record may not capture the full picture of conditions throughout Weilheim i.OB.
