What the data includes

The Grad Zabok air‑quality record draws on two monitoring sites that together provide 21 recent data rows covering seven pollutants: carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), particulate matter of 1 µm (PM₁), 10 µm (PM₁₀) and 2.5 µm (PM₂.₅), and sulfur dioxide (SO₂). All the latest readings were taken on 2026‑02‑10 at 19:00 UTC, so the dataset reflects conditions that are only a few days old.

Across the pollutants the observed values span a fairly wide range. CO varies from a low of about 497 ppb to a high of roughly 1 056 ppb, with a median near 678 ppb; NO is essentially at background levels, ranging from 0 to just under 4 ppb and medalling at zero; NO₂ shows more variation, from 20 ppb up to 85 ppb with a typical value around 30 ppb. Particulate matter also displays notable spread: PM₁ ranges between 3.5 and 52.8 µg/m³ (median 29 µg/m³), PM₂.₅ from 5.1 to 58.6 µg/m³ (median 32 µg/m³), and PM₁₀ from 8.7 to 79.3 µg/m³ (median 44 µg/m³). SO₂ remains low, fluctuating between 1.6 and 2.8 ppb with a median of 1.7 ppb.

The dataset is relatively balanced in terms of freshness—every pollutant has its most recent measurement from the same timestamp—yet the number of rows (21) is modest, meaning that short‑term fluctuations may not be fully captured. Because only two stations contribute data, spatial differences within Grad Zabok are possible, and conditions can change throughout the day beyond what these snapshots show.

Data notes

The data shown for Grad Zabok is based on twelve 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.
