What the data includes

Miercurea Ciuc’s air‑quality feed draws on data from three monitoring stations that together provide seventeen recent observations across five key pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀) and sulfur dioxide (SO₂). All of the latest readings were recorded at 2026‑02‑10 19:00 UTC, which falls within the “updated within seven days” freshness category, so the dataset reflects conditions from a single recent snapshot rather than a continuous stream.

The values show a fairly tight spread for most gases. Ozone sits at 48.09 µg/m³, with the ten‑percentile at 35.79 µg/m³ and the ninety‑percentile just under 49 µg/m³, indicating limited variability around the median of 47.04 µg/m³. Carbon monoxide is recorded at 584.59 µg/m³; its range runs from a low of 526.40 to a high of 661.69 µg/m³, with the middle fifty percent clustered between roughly 538 and 646 µg/m³. Nitrogen dioxide is the lowest‑concentration gas at 5.97 µg/m³, spanning only about five micrograms from its minimum of 5.97 to a maximum of 10.94 µg/m³, while the median sits near 7.79 µg/m³. Particulate matter (PM₁₀) is reported at exactly 10.0 µg/m³ for both the current value and the ten‑percentile, rising to a maximum of 48.21 µg/m³; the ninety‑percentile sits around 40.57 µg/m³, showing that higher spikes are possible but not reflected in the latest point. Sulfur dioxide measures 4.50 µg/m³, with its observed range from 4.29 to 8.99 µg/m³ and a ninety‑percentile near 8.09 µg/m³.

Because the dataset consists of a single recent timestamp for each pollutant, it captures only one moment in time across the three stations. While the measurements are fresh, the limited temporal depth means that day‑to‑day or intra‑city variations are not represented here; conditions can differ by location and over short periods even though the current snapshot provides a concise view of the city’s air quality at that specific hour.

Data notes

The dataset for Miercurea Ciuc includes ten valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 19:00 UTC, meaning it is updated within three days. This snapshot reflects conditions captured at that time; however, air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
