Air quality today
The air quality in Baden‑Baden is classified as Good today. The primary pollutant measured is PM2.5, fine particulate matter, with a reference value of 1.0 µg/m³. Four valid measurements were recorded for the assessment.
PM10 also has a reference value listed at 2.2 µg/m³, reflecting the broader particle size category included in the monitoring data. Data is shown via OpenAQ and reflects the current conditions based on those four observations. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
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 dataset for Baden‑Baden contains a single monitoring row that reports five pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀) and particulate matter ≤ 2.5 µm (PM₂.₅). Because only one station contributes data, the coverage is limited to that location and does not capture spatial variation across the city.
The timestamps show a mixed picture of freshness. The NO measurement is from 2024‑03‑11 11:00 UTC, making it over a year old, while the remaining four pollutants were last updated on 2026‑02‑10 17:00 UTC, which is within the past three days. This means that for most of the reported compounds the data are current, but the NO value reflects an older reading.
All five pollutants have identical minimum, median and maximum values in this row, indicating no observed variability at the station during the reporting period. NO sits at 1.6 µg/m³, NO₂ at 6.125 µg/m³, O₃ at 65.906 µg/m³, PM₁₀ at 2.2 µg/m³ and PM₂.5 at 1.0 µg/m³. Because there is only one data point per pollutant, statistical spread (e.g., inter‑percentile ranges) cannot be assessed beyond the single reported figure.
Overall, the dataset provides a snapshot of current air quality for four pollutants but relies on an outdated NO measurement and lacks multiple stations to represent city‑wide conditions. Users should keep in mind that actual concentrations may differ across neighborhoods and times not captured by this limited sampling.
