Air quality today
The air quality in Aalen today is classified as Moderate. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 13.0 and a PM10 reference value of 17.4, based on five valid observations collected via OpenAQ.
These figures reflect the current monitoring results for the city. 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 Aalen air‑quality dataset contains seven pollutant records collected from a single monitoring station. All six common pollutants—carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter 10 µm or less (PM10), particulate matter 2.5 µm or less (PM2.5) and sulfur dioxide (SO2)—are represented, giving a full picture of the city’s emissions profile.
The most recent measurements were taken on 2026‑02‑10 at 17:00 UTC for NO2, O3, PM10, PM2.5 and SO2, so half of the data reflects conditions from just a few days ago. In contrast, CO and NO are based on older entries, last updated on 2017‑01‑08 19:00 UTC and 2024‑03‑11 11:00 UTC respectively, indicating that those two pollutants have not been refreshed recently. Across the dataset each pollutant shows a single recorded value: CO is consistently 400.0 µg/m³, NO stays at 3.2 µg/m³, NO2 registers 26.771 µg/m³, O3 records 30.234 µg/m³, PM10 measures 17.4 µg/m³, PM2.5 is 13.0 µg/m³ and SO2 reads 3.7 µg/m³. Because every pollutant has only one observation, the reported minimum, median and maximum are identical, providing no insight into variability over time.
With just one monitoring location, the data captures conditions at that specific site but cannot represent spatial differences across Aalen. The mix of very recent timestamps for half the pollutants and older timestamps for the others means that while some aspects of the current air quality are up‑to‑date, other components may not reflect present‑day levels. Users should keep in mind that actual concentrations can differ by neighbourhood and time of day.

Data notes
The data shown are based on five valid measurements and have been updated within 3 days, with the latest refresh recorded at 2026‑02‑10 17:00 UTC. This snapshot reflects conditions captured by the monitoring network at that time; however, air quality can vary across different neighbourhoods and moments throughout Aalen, so values may differ locally or later in the day.
