What the data includes

The dataset for Satu Mare contains recent measurements of five key air‑quality gases and particles – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), sulfur dioxide (SO₂) and particulate matter 10 µm or smaller (PM10). The information comes from nine individual data rows collected at two monitoring stations, all of which were last updated on 2026‑02‑10 19:00 UTC, so the freshest values are less than a week old.

Carbon monoxide shows a wide spread, with recorded concentrations ranging from 342.04 µg/m³ up to 1 027.22 µg/m³ and a median of about 684.63 µg/m³. Nitrogen dioxide varies between 8.39 µg/m³ and 42.10 µg/m³, with a typical value near 25.24 µg/m³. Ozone levels are comparatively tight, ranging from 25.66 µg/m³ to 47.92 µg/m³ and centering around a median of 36.79 µg/m³. Sulfur dioxide is the least variable, staying between 4.16 µg/m³ and 5.72 µg/m³ with a median close to 4.94 µg/m³. PM10 has only a single reported value – 28.52 µg/m³ – because it appears in just one row of the dataset.

Overall, the data are recent but unevenly distributed across pollutants: CO, NO₂, O₃ and SO₂ each have two rows of observations, while PM10 is represented by a single entry. This means that while the latest snapshot reflects current conditions, the limited number of rows for some substances may not capture the full spatial or temporal variability within the city. Consequently, any single reading should be understood as part of a broader picture that can change across different locations and times in Satu Mare.

Data notes

The data shown are based on four valid measurements and were refreshed recently, having been updated within three days (last update 2026‑02‑10T19:00:00+00:00). This snapshot reflects conditions at the time of sampling; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in Satu Mare.
