Air quality today

The air quality in Valthermond today is classified as Good. The primary pollutant identified for the current assessment is PM10, which refers to coarser particulate matter measured in the local monitoring network.

Seven valid measurements were recorded, and the reported PM10 reference value stands at 17.23 micrograms per cubic metre. Data are shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Valthermond air‑quality feed includes four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and particulate matter ≤ 10 µm (PM10). All data come from a single monitoring site, Valthermond‑Noorderdiep, and the dataset contains seven recent rows in total. Every row was last refreshed on 2026‑02‑10 at 21:00 UTC, which places all observations comfortably within the “updated within 7 days” freshness bucket.

Across the pollutants there is a clear difference in how many readings are available. NO₂, O₃ and PM10 each have three recent values, showing a modest spread: NO₂ ranges from 16.8 to 17.8 µg/m³ with a median of 17.3 µg/m³; O₃ varies between 12.86 and 13.44 µg/m³, median 13.15 µg/m³; PM10 spans 9.55 to 17.23 µg/m³, median 13.39 µg/m³. By contrast, NO is represented by a single measurement of 0.39 µg/m³, so no range or median can be derived for that gas.

The data illustrate both breadth and limitation. While the three larger‑sample pollutants give an idea of typical concentrations – each staying within roughly one microgram per cubic metre of its median – the lone NO value means any assessment of nitrogen monoxide in Valthermond would rely on a single point in time. Because all rows are recent, the figures reflect conditions as they were on 2026‑02‑10, but the limited number of stations and the sparse NO record mean that local variations across the city or over longer periods are not captured here.
