Air quality today

The air quality in Krems an der Donau is classified as Good today. The primary pollutant identified is PM10, based on three valid measurements. All three measurements were taken within the same reporting period and are displayed through OpenAQ. No reference value is provided for PM2.5, while the reference value for PM10 is 26.5 µg/m³. The dataset does not include additional pollutant categories for this assessment.

The current PM10 concentration aligns with the reference value of 26.5 µg/m³ reported by OpenAQ. This concentration is expressed in micrograms per cubic meter. The figure reflects the measurements available for the city at this time and does not represent a trend analysis. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The data for Krems an der Donau comes from a single OpenAQ monitoring station and consists of nine measurement rows that together report five pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter 10 µm or less (PM10) and sulfur dioxide (SO2). Each row records a value in micrograms per cubic metre and the time it was last updated, giving a snapshot of what the sensor network has captured for the city.

Freshness varies across the set. Three of the rows have been refreshed within the last three days, all of them for NO2, O3 and PM10 with the most recent timestamp of 2026‑02‑10 20:00 UTC. The SO2 reading is older, last updated on 2025‑12‑31 00:00 UTC, while the NO measurement dates back to 2024‑03‑11 12:00 UTC. In total, six rows are classified as “old”, meaning that for much of the recent period the city’s air‑quality picture relies on data that is several months or years out of date.

The numeric spread shows that NO2 values range from about 11.8 µg/m³ at the low end to 16.0 µg/m³ at the high end, with a median near 13.9 µg/m³. O3 varies between 24.4 µg/m³ and 41.0 µg/m³, centering on a median of 32.7 µg/m³. PM10 shows a broader interval, from 6.0 µg/m³ up to 26.5 µg/m³, with a median of 16.3 µg/m³. SO2 is the only pollutant with a negative reading, ranging from –1.0 µg/m³ to 1.0 µg/m³ and a median of zero. NO is represented by a single value of 4.37 µg/m³. These figures illustrate that the dataset captures a modest range of concentrations, but the uneven timing and the limited number of recent observations mean that conditions in Krems can differ across locations and moments that are not fully reflected in the current data.
