What the data includes

The Strumica air‑quality dataset contains measurements for six pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀) and particulate matter ≤ 2.5 µm (PM₂.₅). The data come from 13 individual rows recorded at four monitoring stations across the city.

Most of the recent observations were uploaded within the past week, with the latest timestamps dated 2026‑02‑10 19:03 UTC for PM₂.₅ and 2026‑02‑10 18:00 UTC for NO₂, O₃ and PM₁₀. These newer entries show a PM₂.₅ range from 7.24 to 22.42 µg/m³, a median of 13.0 µg/m³ and a 90th‑percentile value of 18.652 µg/m³, indicating modest variability among the recent samples. NO₂, O₃ and PM₁₀ each have a single recorded value (3.056 µg/m³, 28.2 µg/m³ and 24.9 µg/m³ respectively), all updated on the same day.

In contrast, CO and NO are represented only by older records from 2024‑03‑11 12:00 UTC. The lone CO reading is 613.64 µg/m³ and the single NO value is 3.25 µg/m³; both are flagged as “old data,” highlighting a gap in recent coverage for these gases. Overall, while the dataset provides fresh information for particulate matter and ozone‑related compounds, it lacks up‑to‑date measurements for carbon monoxide and nitrogen oxide, meaning current conditions for those pollutants cannot be assessed from this source alone. The mix of recent and outdated entries underscores that air quality can differ across locations and times within Strumica.

Data notes

The data shown for Strumica is based on ten valid measurements and was updated within 3 days, with the latest refresh recorded at 2026‑02‑10T19:03:39+00:00. This snapshot reflects conditions captured by the monitoring network at that time; however, air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment within the city.
