What the data includes

Ludwigsburg’s OpenAQ feed supplies data for five pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM10) and particulate matter ≤2.5 µm (PM2.5). The dataset contains eight rows drawn from three monitoring stations, so the spatial coverage is limited to a few fixed points rather than city‑wide sampling.

The most recent measurements are from 2026‑02‑10 18:00 UTC for NO₂, O₃, PM10 and PM2.5, while the latest NO reading dates back to 2024‑03‑11 11:00 UTC, indicating that nitrogen monoxide data are older than the other pollutants. Across the recent records, NO₂ values range from a low of 14.39 µg/m³ to a high of 49.06 µg/m³ with a median of 43.08 µg/m³; NO spans 2.80 µg/m³ up to 49.40 µg/m³, median 26.10 µg/m³. O₃ is reported as a single value of 58.58 µg/m³, and both PM10 and PM2.5 appear only once at 3.7 µg/m³ and 2.0 µg/m³ respectively.

Because most rows are recent but the overall number of observations is small, the data give a snapshot rather than a detailed picture of city‑wide air quality. The spread in NO₂ and NO suggests variability between the monitored sites, whereas ozone and particulate matter show no observed variation within this limited sample. Users should keep in mind that conditions can differ across neighborhoods and times not captured by these few, mostly fresh records.
