What the data includes

The dataset for Tehuacán pulls information from a single monitoring site that reported eight separate rows of data, one for each of the measured pollutants: carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), ozone (O₃), particulate matter 10 µm or smaller (PM₁₀), particulate matter 2.5 µm or smaller (PM₂.₅) and sulfur dioxide (SO₂). All eight entries were last refreshed on 2026‑02‑10 at 22:00 UTC, which falls within the “updated within 7 days” freshness bucket, so the values represent a very recent snapshot of air quality in the city.

Because there is only one active station, each pollutant is represented by a single measurement rather than a distribution across multiple locations. Consequently, the reported minimum, median and maximum are identical for every compound: CO stands at 2.0158 ppm, NO at 0.00313 ppm, NO₂ at 0.01997 ppm, NOX at 0.02311 ppm, O₃ at 0.02872 ppm, PM₁₀ at 31.10 µg/m³, PM₂.₅ at 7.47 µg/m³ and SO₂ at 0.00189 ppm. The lack of variation means the dataset cannot illustrate temporal or spatial spreads for these pollutants in Tehuacán.

With just one monitoring location, coverage is limited to the conditions measured at that point on a single day. While the data are fresh, they do not capture possible differences across neighborhoods or changes over time. Users should keep in mind that air quality can fluctuate throughout the city and that additional stations would be needed to provide a fuller picture of overall atmospheric conditions.
