Air quality today

The air quality in Essen today is classified as Good. The primary pollutant measured is PM2.5, with a recorded concentration of 3.942 µg/m³. In addition, PM10 levels were observed at 10.114 µg/m³ based on twelve valid measurements.

Data are shown via OpenAQ and reflect the current assessment for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Essen’s open‑air quality feed contains six measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀), particulate matter ≤ 2.5 µm (PM₂.₅) and sulphur dioxide (SO₂). The data set comprises 20 individual rows drawn from five monitoring stations across the city, so each pollutant is represented by a handful of observations rather than a dense network.

The most recent values are generally very fresh: NO₂, PM₂.5, O₃ and SO₂ were all recorded on 2026‑02‑10 between 16:00 UTC and 18:00 UTC, while the latest PM₁₀ reading comes from 2026‑02‑10 17:00 UTC. NO is the exception, with its newest entry dated 2024‑03‑11 11:00 UTC, which means that for this pollutant the available figure is older than two years. Across all pollutants the median concentrations are modest – NO sits at 23.978 µg/m³, NO₂ at 20.55 µg/m³, O₃ at 31.796 µg/m³, PM₁₀ at 9.253 µg/m³, PM₂.5 at 6.1495 µg/m³ and SO₂ at a constant 3.699 µg/m³ – while the observed ranges show considerable spread for gases (NO varies from 0.383 to 51.011 µg/m³) and narrower bands for particles (PM₁₀ from 7.913 to 10.114 µg/m³, PM₂.5 from 3.942 to 11.737 µg/m³).

Because the station coverage is uneven – only one row supplies NO data and a single row provides SO₂ – the picture of city‑wide air quality is limited in detail. The freshest timestamps suggest that most pollutants are being reported within the last few days, yet the older NO measurement highlights gaps that can affect how representative the snapshot is for any given location or moment in Essen.

Data notes

The dataset for Essen includes twelve valid measurements and is refreshed regularly, having been updated within three days (last update: 2026‑02‑10T18:00:00+00:00). These values represent a snapshot of the city’s air quality at specific monitoring points; conditions can differ across neighborhoods and change throughout the day. Consequently, the figures shown should be interpreted as an indicative overview rather than a precise, location‑by‑location reading.
