What the data includes

The dataset for Mediaș contains measurements from 13 data rows collected at two monitoring stations. Five pollutants are represented: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and sulfur dioxide (SO₂). The most recent updates are fairly fresh for three of them – NO₂, SO₂ and PM₁₀ were last recorded on 2026‑02‑10 at 19:00 UTC, which is within the past week. In contrast, O₃ and CO have not been updated since 2025‑11‑15 at 08:00 UTC, so their values are several months old.

For NO₂ the median concentration across the recent rows is 20.50 µg/m³, with a minimum of about 1.29 µg/m³ and a maximum of 23.16 µg/m³; the 10th‑percentile sits near 5.13 µg/m³ and the 90th‑percentile around 22.63 µg/m³, indicating most recent readings cluster in the low‑to‑mid twenties. SO₂ shows a median of 5.23 µg/m³, ranging from just above zero (0.25 µg/m³ at the 10th percentile) to roughly 11.89 µg/m³, with the upper 90th‑percentile close to 10.56 µg/m³. PM₁₀ values are tightly grouped: the median is 13.85 µg/m³, the minimum recorded is 13.14 µg/m³ and the maximum 14.57 µg/m³; the inter‑percentile spread (13.28–14.42 µg/m³) is narrow, suggesting little variation in recent particulate measurements.

The older O₃ data show a median of –1.0 µg/m³ with a maximum of about 7.18 µg/m³, while CO reports an implausible constant value of –1000.0 µg/m³ for all its rows, reflecting either sensor error or missing data. Because half of the pollutants have recent observations but two remain outdated, the picture of air quality in Mediaș is incomplete; conditions can differ across locations and times, especially where only older measurements are available.

Data notes

The data shown for Mediaș is based on five valid measurements and was refreshed recently, with the latest update recorded at 2026‑02‑10T19:00:00+00:00 (updated within 3 days). 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 the city.
