Air quality today
The air quality in Nestelbach bei Graz is classified as USG. The primary pollutant identified is PM2.5 (fine particles). The latest PM2.5 measurement is 45.28 µg/m³, based on five valid observations. Data is shown via OpenAQ. All values are reported in micrograms per cubic meter, the standard unit for particulate matter.
The reported PM2.5 concentration reflects the current atmospheric condition for the city. No PM10 value is available for this assessment. The measurement count of five indicates the number of data points used to derive the presented figure. The data represent a snapshot of ambient conditions and are not aggregated over longer periods. 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 Nestelbach bei Graz air‑quality feed contains six individual rows of data collected by a single monitoring station. All six standard pollutants are represented: PM1, PM10, PM2.5, relative humidity, temperature and the particle counter UM003. Five of the rows were recorded within the last three days, the most recent timestamp being 2026‑02‑10 21:00 UTC, while one row – the PM10 measurement – dates back to 2025‑01‑13 23:00 UTC, making it the only “old” entry in the set.
Each pollutant currently has a single reported value, so the minimum, median and maximum are identical. PM1 registers at 24.136166667938237 µg/m³, PM10 at 21.245500246683758 µg/m³, and PM2.5 at 45.278333028157554 µg/m³. Relative humidity is measured at 67.62566655476888 %, temperature at 8.519166739781697 °C, and the UM003 particle concentration at 3 575.625 particles/cm³. Because there is no spread of values for any parameter, the data describe a snapshot rather than a range of conditions.
The dataset’s composition highlights two practical points. First, the station coverage is limited to one location, so the figures reflect conditions at that specific site and may not capture spatial variations across the wider city area. Second, the freshness of the data is generally high for most pollutants, but the older PM10 reading indicates an uneven update frequency, which could affect short‑term comparisons. Users should keep in mind that the current snapshot provides a recent but singular view of Nestelbach’s air quality.
