Air quality today
The air quality in Soest today is classified as Good. The primary pollutant identified is PM2.5 (fine particles).
Measurements from four valid monitoring stations show a PM2.5 reference value of 4.873 and a PM10 reference value of 6.738. These figures are presented through OpenAQ data 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 dataset for Soest in North‑Rhine Westphalia contains measurements for five key pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or smaller (PM₁₀) and particulate matter 2.5 µm or smaller (PM₂.₅). All values are reported in micrograms per cubic metre (µg/m³). The source consists of a single monitoring location, Soest‑Ost, which provides one row of data for each pollutant, giving a total of five rows.
Freshness varies across the series. The NO reading is dated 2024‑03‑11 11:00 UTC and is flagged as “Old data”, making it the oldest entry in the set. All other pollutants – NO₂, O₃, PM₁₀ and PM₂.₅ – were last updated on 2026‑02‑10 17:00 UTC and are marked as “Updated within 3 days”. This means that four of the five measurements reflect conditions from just a few hours ago, while the NO value is more than two years old.
Because each pollutant has only one recorded figure, the statistical spread is effectively zero: the minimum, median, maximum, 10th percentile and 90th percentile are identical for every parameter. For example, NO₂ registers exactly 8.204 µg/m³, O₃ 49.995 µg/m³, PM₁₀ 6.738 µg/m³ and PM₂.5 4.873 µg/m³ at the Soest‑Ost site. The uniformity of these single‑point values highlights that the current dataset offers a snapshot rather than a range of conditions, and it reflects only one location within the city. Consequently, while the recent timestamps for most pollutants suggest up‑to‑date information, the limited spatial coverage and the outdated NO measurement mean that air quality can still differ across other parts of Soest and at other times.

Data notes
The data shown for Soest are based on four valid measurements and were refreshed recently, with the latest update recorded at 2026‑02‑10T17:00:00+00:00 (updated within 3 days). This snapshot reflects conditions at the time of sampling; air quality can differ across neighbourhoods and change throughout the day, so values may not represent every location or moment in the city.
