Air quality today

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

Measurements recorded by OpenAQ show a PM2.5 concentration of 11.0101 µg/m³ and a PM10 level of 14.48455 µg/m³, based on six valid observations. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Koblenz contains measurements for seven pollutants – carbon monoxide, nitrogen oxide, nitrogen dioxide, ozone, particulate matter ≤ 10 µm, particulate matter ≤ 2.5 µm and sulphur dioxide – collected from three monitoring stations. Overall the newest reading in the set is from 2026‑02‑10 18:00 UTC (NO₂, PM2.5 and PM10), while the oldest recent entry dates back to 2024‑03‑11 11:00 UTC for NO; a single SO₂ value is even older at 2025‑04‑24 12:00 UTC. This means that most pollutants have data updated within the last few days, but some (CO, O₃ and especially SO₂) rely on a single recent point and lack broader temporal coverage.

Across the three stations the recorded values show modest variation. NO ranges from about 12.1 to 52.9 µg/m³ with a median of 12.38 µg/m³, indicating that most observations sit near the lower end of the range. NO₂ spans 24.4‑48.8 µg/m³ and clusters around a median of 40.77 µg/m³, while PM2.5 values are tightly grouped between 10.64 and 11.01 µg/m³ (median ≈ 10.83 µg/m³). PM10 shows a broader spread from 14.48 to 23.14 µg/m³ with a median of 18.81 µg/m³. The single CO reading is 392.994 µg/m³ and the lone O₃ measurement is 20.7707443 µg/m³, both reported from the same station at the same recent timestamp.

Because only three rows contribute to the whole set, the coverage is limited and not uniform across pollutants; some chemicals are represented by multiple recent observations (NO₂, PM2.5, PM10) while others rely on a single point that may not reflect current conditions throughout the city. Consequently, air‑quality snapshots for Koblenz can differ noticeably depending on location and time of measurement.
