Air quality today

The overall air quality today is classified as USG. The main pollutant is PM2.5, with a measured concentration of 48.0 µg/m³ based on five valid observations. The reported PM2.5 value reflects the latest available reading for Leobersdorf, Lower Austria. No PM10 measurement is reported for the current period.

These data are shown via OpenAQ and represent an aggregation of five valid measurements from local monitoring stations. The five valid measurements were recorded within the past 24 hours, providing a snapshot of current atmospheric conditions. The concentration figure is expressed in micrograms per cubic meter, the standard unit for particulate matter reporting. These figures are intended for public awareness and are not a substitute for professional environmental assessments. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Leobersdorf air‑quality record comes from a single monitoring station that has contributed six data rows. Five of those rows were captured within the last three days, while one row dates back to early January 2025, giving the overall dataset a fairly recent profile but with a single older entry for one pollutant. The available measurements cover the full suite of typical urban air‑quality parameters: fine particulate matter (PM1, PM2.5, PM10), a particle‑count metric (UM003), and basic meteorological variables (relative humidity and temperature). All pollutants except PM10 show a last‑updated timestamp of 2026‑02‑10 21:00 UTC, indicating that the most recent snapshot was taken at that moment; PM10’s most recent entry is from 2025‑01‑13 23:00 UTC, which is considerably older.

At the moment each pollutant is represented by a single recorded value, so the dataset does not provide a range or spread for any of them. PM1 is reported at 27.697166665395102 µg/m³, PM2.5 at 48.01149978637696 µg/m³, and PM10 at 19.18374999364217 µg/m³. The particle‑count sensor (UM003) reads 4773.258333333334 particles/cm³, the relative humidity is 64.29999980926515 %, and the temperature is 8.346666542689006 °C. Because each metric has identical minimum, median and maximum values, the current data set offers a point‑in‑time picture rather than a statistical distribution.

Given that the information originates from only one location, it captures conditions at that specific site but cannot describe variations across different neighbourhoods or times of day. Users should keep in mind that the city’s air quality may change elsewhere or later, and that the older PM10 entry highlights an uneven update frequency among the measured parameters.
