What the data includes

The OpenAQ feed for Tlaxcala de Xicohténcatl contains a single monitoring location – the Palacio de Gobierno – so all eight measured pollutants (CO, NO, NO₂, NOₓ, O₃, PM10, PM2.5 and SO₂) are reported from one row of data. The most recent timestamp across the set is 2026‑02‑10 22:00 UTC for NO, NO₂, NOₓ, PM10 and PM2.5, indicating that half of the pollutants have been updated within the last seven days. CO (last updated 2025‑03‑21 21:00 UTC), O₃ (2025‑04‑14 20:00 UTC) and SO₂ (2025‑06‑09 02:00 UTC) are older, with dates ranging from eight months to over a year ago.

Across the pollutants the reported values are single-point measurements rather than ranges. CO is recorded at 3.584 ppm, NO at 0.00649 ppm, NO₂ at 0.00559 ppm, NOₓ at 0.01208 ppm and O₃ at 0.00181 ppm. Particulate matter shows a higher concentration: PM10 is 75.59 µg/m³ and PM2.5 is 16.55 µg/m³. SO₂ registers at 0.00301 ppm. Because each pollutant has only one recorded value, the median, minimum and maximum are identical for every metric.

The data set therefore provides a snapshot rather than a distribution, with fresh updates available for five of the eight pollutants but older information for the remaining three. With only one monitoring site, spatial variation within the city cannot be captured, so conditions may differ in other neighborhoods or at different times of day.

Data notes

The current dataset for Tlaxcala de Xicohténcatl includes five valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 22:00 UTC; it is therefore considered updated within three days. This snapshot reflects conditions captured at that time, but air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
