Air quality today
The air quality in Heidenreichstein, Lower Austria is currently classified as Good. The primary pollutant identified is PM10, and four valid measurements have been recorded for the assessment. The most recent PM10 reading is 18.0 µg/m³, which corresponds to the reference value used in the evaluation. No reference value is available for PM2.5, so the assessment relies on the PM10 data. The Good category reflects that the measured PM10 concentration does not exceed the reference threshold.
The figures represent the latest available data for the location. Measurements are aggregated from local monitoring stations. All values are displayed via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The Heidenreichstein 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) – all recorded at a single monitoring site (Heidenreichstein Thaures). In total the dataset holds six rows, one for each pollutant, drawn from that one station.
Freshness varies across the pollutants. Four of the six rows were updated within the last three days, with the most recent timestamps on 2026‑02‑10 20:00 UTC for NO₂, O₃, PM₁₀ and SO₂. The remaining two rows are older: the NO value dates from 2024‑03‑11 12:00 UTC and the PM₂.₅ measurement from 2023‑08‑01 12:00 UTC. This mix means that while most of the data reflects current conditions, a minority of the values are dated and may not represent today’s air quality.
Each pollutant is represented by a single reported concentration, so the minimum, median and maximum are identical. NO registers at 0.81 µg/m³, NO₂ at 8.41 µg/m³, O₃ at 34.72 µg/m³, PM₁₀ at 18.0 µg/m³, PM₂.₅ at 3.95 µg/m³ and SO₂ at 1.80 µg/m³. Because there is no spread of values, the dataset cannot illustrate short‑term fluctuations or trends for any of the substances. The overall picture is therefore a snapshot of six key pollutants from one location, with most readings recent but two older entries that limit a complete, up‑to‑date view of the city’s air quality at all times.
