What the data includes

The Kadıköy air‑quality dataset contains measurements for carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter of three size fractions (PM₁, PM₂.5 and PM₁₀), sulphur dioxide (SO₂), temperature, relative humidity and a miscellaneous variable labelled UM003. In total the source provides 40 rows of data collected from 11 distinct monitoring stations. Of those rows, 19 have been recorded within the last seven days, another 19 are classified as “old” (recorded more than thirty days ago) and two lack a clear timestamp.

The most recent values for each pollutant come from different dates. The latest PM₂.5 reading is 36.88 µg/m³ reported on 2026‑02‑10 at 19:00 UTC, while the same timestamp applies to PM₁₀ (36.88 µg/m³) and temperature (7.16 °C). Ozone’s newest entry is older, dated 2025‑09‑19 at 09:00 UTC with a value of 2.37 µg/m³. Carbon monoxide, nitrogen dioxide and sulphur dioxide each have a single observation from 2023‑10‑11 at 10:00 UTC, reporting 269.988 µg/m³, 26.4 µg/m³ and 2.9 µg/m³ respectively. The lone PM₁ measurement comes from 2025‑06‑17 at 05:00 UTC with a value of 16.75000015894572 µg/m³.

Across the recent seven‑day window, particulate matter shows a fairly wide spread: PM₂.5 values range from about 9.7 to 61.2 µg/m³ with a median near 29 µg/m³, and PM₁₀ ranges from roughly 16.2 to 112.2 µg/m³ with a median of 40 µg/m³. Temperature varies between 6.05 °C and 28.70 °C, centering on a median of 13.48 °C. By contrast, the data for gases such as CO, NO₂, SO₂ and O₃ are limited to single historic points, making it difficult to assess current variability. Overall, while particulate and temperature measurements are relatively fresh and numerous, many key pollutants rely on older or sparse records, so the picture of Kadıköy’s air quality can differ noticeably across locations and times.
