What the data includes

The Copșa Mică air‑quality record draws on twelve data rows collected at two monitoring sites and covers five measured pollutants: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀) and sulfur dioxide (SO₂). For NO₂, PM₁₀ and SO₂ the most recent observations were uploaded on 2026‑02‑10 at 19:00 UTC, so these three gases have fresh data that are “updated within 7 days.” The CO values come from a single entry dated 2025‑11‑15 at 09:00 UTC and are flagged as old, while the O₃ measurement is even older, recorded on 2022‑04‑28 at 07:00 UTC.

Across the three recently refreshed pollutants the observed concentrations span a wide range. NO₂ varied from about 12.8 µg/m³ up to 123.7 µg/m³, with a median of 13.7 µg/m³ and a 10th‑percentile near 13.0 µg/m³, indicating most recent readings cluster close to the lower end while occasional higher spikes are present. PM₁₀ showed values from roughly 0.2 µg/m³ to 29.4 µg/m³, median 28.6 µg/m³ and a 90th‑percentile of 29.25 µg/m³, suggesting the recent data are dominated by higher particulate levels. SO₂ remained tightly bounded between about 5.1 µg/m³ and 11.9 µg/m³, median 5.27 µg/m³, with little variation beyond the lower‑mid range.

The dataset is uneven: three pollutants have current measurements, while CO and O₃ rely on older entries that may not reflect present conditions. Because only two stations contribute data, spatial coverage within Copșa Mică is limited, meaning air quality can differ across neighborhoods and times that are not captured by the available rows.
