Air quality today
The air quality in Solingen today is classified as Good. The primary pollutant measured is PM10, with a reported reference value of 6.12 micrograms per cubic metre based on three valid observations.
Data are shown via OpenAQ and reflect the current monitoring results for this location. 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 Solingen air‑quality dataset contains measurements for five pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and particulate matter 2.5 µm or less (PM₂.₅). The data come from eight individual rows, but only two distinct monitoring stations are represented: Solingen‑Wald supplies the recent values for NO, NO₂, PM₁₀ and O₃, while a separate site identified as DENW206 provides the single PM₂.5 reading.
Freshness varies across the pollutants. The most up‑to‑date observations were recorded on 2026‑02‑10 at 17:00 UTC for NO₂, PM₁₀ and O₃, and on 2024‑03‑11 at 11:00 UTC for NO. In contrast, the PM₂.5 value is older, dated 2023‑07‑14 at 10:00 UTC, and no rows are flagged as unknown or missing.
Across the recent measurements, NO ranges from a low of 1.91 µg/m³ to a high of 17.50 µg/m³, with a median around 9.70 µg/m³, indicating modest variability at the Solingen‑Wald site. NO₂ shows a broader spread, from 12.73 µg/m³ up to 33.79 µg/m³ and a median of roughly 23.26 µg/m³. PM₁₀ values are tightly clustered between 6.12 and 11.91 µg/m³, with a median near 9.02 µg/m³, while O₃ is reported as a single constant value of 37.122 µg/m³ for the latest timestamp. The lone PM₂.5 reading stands at 5.191 µg/m³ and has not been updated since mid‑2023.
Overall, the dataset offers recent coverage for four pollutants from one well‑instrumented location, but the PM₂.5 data are sparse and dated, highlighting that air‑quality conditions in Solingen can differ by pollutant, monitoring site and time of measurement.
