What the data includes

The Cadereyta Jiménez air‑quality feed contains eight measured pollutants – carbon monoxide (CO), nitric oxide (NO), nitrogen dioxide (NO₂), total oxides of nitrogen (NOX), ozone (O₃), particulate matter 10 µm or less (PM₁₀), particulate matter 2.5 µm or less (PM₂.₅) and sulfur dioxide (SO₂). All data come from a single monitoring station that has contributed 16 recent rows, each refreshed on 2026‑02‑10 at 22:00 UTC, so the information is uniformly fresh across every pollutant.

The recorded values show modest variability. CO spans from 1.0 to 1.33 ppm with a median of 1.165 ppm; NO ranges between 0.0028 and 0.0056 ppm (median 0.0042 ppm); NO₂ varies from 0.0071 to 0.010 ppm (median 0.00855 ppm); NOX covers 0.0098‑0.0154 ppm (median 0.0126 ppm). Ozone is the most variable, ranging from 0.021 to 0.051 ppm with a median of 0.036 ppm. Particulate matter shows tighter bands: PM₁₀ is between 37 and 46 µg/m³ (median 41.5 µg/m³) and PM₂.₅ stays from 21 to 23 µg/m³ (median 22 µg/m³). SO₂ is the least variable, recorded from 0.0057 to 0.0058 ppm with a median of 0.00575 ppm.

Because all rows are recent and come from one location, the dataset captures a snapshot rather than city‑wide spatial diversity. The narrow spreads for most pollutants suggest relatively stable conditions at this site during the reporting period, while ozone’s broader range hints at greater short‑term fluctuation. Users should keep in mind that air quality can differ across neighborhoods and over time, and the current figures reflect only the latest measurements from this single monitoring point.

Data notes

The dataset for Cadereyta Jiménez includes eight valid measurements and is marked as Updated within 3 days, with the most recent values recorded on 2026‑02‑10 at 22:00 UTC. This snapshot reflects conditions at a single point in time; air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured by these figures.
