Air quality today

The air quality in Ratingen today is classified as Good. According to the Duck score, the main pollutant is PM2.5. The reported PM2.5 concentration is 3.182 µg/m³, and the PM10 concentration is 5.05 µg/m³. These figures are based on nine valid measurements collected for this assessment.

Data is shown via OpenAQ, providing the values used in this summary. The Duck assessment incorporates the nine measurements to determine the Good category. The sampling period reflects recent data, and the values represent average concentrations over that interval. All reported figures are consistent with the criteria used by the Duck scoring methodology. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Ratingen air‑quality record pulls together 16 measurement rows from three monitoring sites, of which nine rows have been refreshed within the last 30 days while the remaining seven are older. The dataset supplies values for nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter in three size fractions (PM₁, PM₂.₅ and PM₁₀), relative humidity and temperature; a sensor labelled UM003 is listed among the monitored species but no recent observations are present for it in the current feed.

Across the recent entries, PM₁₀ values range from a low of 5.05 µg/m³ to a high of 35.36 µg/m³ with a median of about 13.48 µg/m³, while PM₂.₅ spans 3.18 µg/m³ to 36.08 µg/m³ and centers near 10.05 µg/m³. The NO₂ and O₃ measurements are tightly clustered, each staying between roughly 25.44 µg/m³ and 26.31 µg/m³ with medians of 25.68 µg/m³ and 25.87 µg/m³ respectively. In contrast, NO shows a broader spread from 0.78 µg/m³ up to 11.58 µg/m³ and a median of 6.18 µg/m³, but its most recent reading dates back to 2024‑03‑11, making it the oldest pollutant record in the set. The single‑row observations for PM₁, relative humidity and temperature all come from the Europaring7 site and were last updated on 2026‑01‑31, reporting 19.36 µg/m³, 62.62 % and 9.72 °C respectively.

Overall the data give a fairly fresh picture for most pollutants, yet the uneven timing—especially the dated NO figure—means that conditions can differ across the city and over time. Users should keep in mind that the limited number of stations and the mix of recent and older rows may not capture short‑term spikes or localized variations fully.
