Air quality today

The air quality in Wernigerode today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles).

Measurements from seven valid monitoring points show a PM2.5 reference value of 13.08141 and a PM10 reference value of 14.584013. These figures are presented through OpenAQ data. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Wernigerode air‑quality record consists of two monitoring rows, each providing a full set of seven pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter 10 µm (PM10), particulate matter 2.5 µm (PM2.5) and sulphur dioxide (SO2). The data are drawn from the single station identified as Wernigerode/Bahnhof, so spatial coverage within the city is limited to that location.

Freshness varies across the series. The most recent updates were recorded on 2026‑02‑10 at 17:00 UTC for CO, NO2, O3, SO2, PM10 and PM2.5, while the NO measurement dates back to 2024‑03‑11 at 11:00 UTC, making it the oldest entry among the seven. All pollutants except NO have been refreshed within the last three days, indicating a generally current picture for most compounds.

The numeric spread shows that CO is reported as a single value of 287.543 µg/m³, and PM10 and PM2.5 each appear only once at 14.584013 µg/m³ and 13.08141 µg/m³ respectively. In contrast, the nitrogen oxides and ozone have multiple observations that allow calculation of ranges: NO varies from a minimum of 0.2155085 to a maximum of 1.68192 µg/m³ with a median near 0.95 µg/m³; NO2 spans 3.73731‑12.56445 µg/m³ with a median of 8.15088 µg/m³; O3 ranges from 53.9293 to 66.4128 µg/m³, median 60.17105 µg/m³. Sulphur dioxide is tightly clustered between 0.477824 and 0.5283875 µg/m³, median 0.50310575 µg/m³.

Because the dataset relies on just two rows from a single monitoring site, it captures only a snapshot of conditions at that point in the city. Variability across pollutants is evident – some have multiple readings showing modest spread, while others are represented by a solitary value. Users should keep in mind that air quality can differ elsewhere in Wernigerode and over time beyond the timestamps provided.

Data notes

The current dataset for Wernigerode includes seven valid measurements and was updated within three 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 differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
