Air quality today
The air quality in Netphen today is classified as Good. The main pollutant identified is PM2.5, with a measured reference value of 6.627 µg/m³. A concurrent measurement for PM10 shows a reference value of 6.647 µg/m³, based on four valid observations reported through OpenAQ.
Overall conditions meet the criteria for the Good category according to the latest assessment. 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 Netphen air‑quality record contains a single monitoring station – the Netphen Rothaargebirge site – which supplies data 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). Because there is only one row of observations, the dataset does not capture spatial variation across the city; it reflects conditions at that specific location.
The timestamps show a mixed picture of freshness. The NO measurement is from 2024‑03‑11 10:00 UTC and is flagged as “Old data,” while the remaining four pollutants were all last updated on 2026‑02‑10 17:00 UTC, which falls within the “Updated within 3 days” category. Thus, for most pollutants the information is very recent, but the NO value is more than a year old.
All five pollutants have a single reported value, so the minimum, median and maximum are identical for each. NO registers at 0.013 µg/m³, NO₂ at 12.315 µg/m³, O₃ at 36.9 µg/m³, PM₁₀ at 6.647 µg/m³ and PM₂.₅ at 6.627 µg/m³. Because there is no spread of measurements, the dataset cannot illustrate variability over time or across locations; it simply provides a snapshot for each pollutant at the moment of the latest update.
In summary, Netphen’s public air‑quality feed offers current readings for four pollutants and an older reading for NO, all sourced from one monitoring point. Users should keep in mind that conditions can differ elsewhere in the city or change after the last update, especially for the nitrogen monoxide value which is over a year out of date.
