Air quality today

The air quality today in Salzburg is classified as Moderate. The primary pollutant measured is PM2.5. The latest PM2.5 reading is 17.7 µg/m³, and the PM10 level is 36.5 µg/m³. Seven valid measurements contributed to this assessment. Data is shown via OpenAQ. PM2.5 refers to fine particulate matter with a diameter of 2.5 micrometers or less, while PM10 includes particles up to 10 micrometers. The reported values are based on data recorded at 2026-02-12 09:00 UTC.

These values reflect the current atmospheric conditions as captured by the monitoring network. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Salzburg pulls hourly readings from six monitoring stations, giving a total of 31 individual rows. All seven common urban pollutants are represented: carbon monoxide (CO), nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀), particulate matter ≤ 2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). The most recent measurements for most pollutants were recorded on 2026‑02‑10 20:00 UTC, while the SO₂ data dates back to 2025‑12‑31 00:00 UTC and the NO data to 2024‑03‑11 12:00 UTC. Across the whole set, eight rows have been updated within the last three days, one row within the last thirty days, and the remaining twenty‑two rows are older than thirty days.

Looking at the numbers, CO shows a median concentration of 256.08 µg/m³ with a maximum of 392.27 µg/m³, indicating a relatively high spread compared with the other gases. NO₂’s median is 31 µg/m³ and its peak reaches 44.65 µg/m³, while PM₁₀ and PM₂.₅ have medians of 12 µg/m³ and 14.74 µg/m³ respectively, with maximum values of 36.51 µg/m³ and 17.69 µg/m³. O₃ is centred around a median of 12.57 µg/m³ and can rise to 43 µg/m³. SO₂ is the only pollutant with a negative placeholder value (‑1.0 µg/m³) in the most recent row, and its median sits at 1.50 µg/m³ with a maximum of 3.20 µg/m³. NO, recorded less frequently, has a median of 6.58 µg/m³ and a maximum of 9.67 µg/m³.

These figures illustrate that while the city’s monitoring network captures a full suite of pollutants, the data freshness is uneven: most gases have very recent values, but SO₂ and NO rely on older observations. The concentration ranges also vary widely, with CO and O₃ showing the broadest spreads, whereas PM₂.₅ remains within a tighter band. Because many rows are older than a month, the snapshot may not reflect short‑term fluctuations that can differ across neighborhoods and times of day.

Data notes

The data shown are based on seven valid measurements and have been updated within 3 days, with the latest update recorded at 2026-02-10T20:00:00+00:00. This snapshot reflects conditions at the time of collection, but air quality can vary by location and time within the city. Users should consider these limitations when interpreting the values presented.
