Air quality today

The air quality in Apizaco, Tlaxcala is currently classified as Moderate. The primary pollutant identified for today is PM10 (coarser particles).

Measurements from eight valid samples show a PM2.5 reference value of 7.0 µg/m³ and a PM10 reference value of 80.6034482758621 µg/m³. These figures reflect the concentrations recorded by OpenAQ during the reporting period.

What the data includes

The Apizaco air‑quality feed contains eight recent measurement rows from a single monitoring site located at the Centro de Salud. All eight standard pollutants tracked by OpenAQ are represented: carbon monoxide (CO), nitric oxide (NO), nitrogen dioxide (NO₂), total oxides of nitrogen (NOX), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀), particulate matter ≤ 2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). The most recent timestamps cluster within the last three days for seven of the eight parameters, with CO, NO₂, NOX, O₃, PM₁₀ and SO₂ all recorded at 2026‑02‑10 22:00 UTC. Nitric oxide is slightly older, logged on 2026‑02‑10 19:00 UTC, while the PM₂.5 reading dates back to 2026‑02‑08 01:00 UTC, a full seven days before the current date.

Across the dataset each pollutant shows a single recorded value, so the reported minimum, median and maximum are identical. CO registers at 0.480133386671242 ppm, NO is extremely low at 1.32785919129219e‑07 ppm, NO₂ measures 1.49055869948834e‑05 ppm and NOX appears at 1.4644556141910001e‑05 ppm. Ozone stands out with a concentration of 0.0947768683009678 ppm. Particulate matter shows a PM₁₀ level of 80.6034482758621 µg/m³ and a PM₂.5 level of 7.0 µg/m³, while sulfur dioxide is recorded at 3.87311732106033e‑06 ppm. Because each pollutant has only one observation, there is no spread to describe; the dataset therefore provides a snapshot rather than a range of variability.

Overall the data are fairly fresh for most pollutants, but the seven‑day lag on PM₂.5 and the single‑station coverage mean that conditions can differ across Apizaco and may have changed since the last measurement. Users should keep in mind that this limited spatial and temporal sampling captures only one point in time at one location within the city.

Data notes

The dataset for Apizaco includes eight valid measurements and was refreshed recently, Updated within 3 days, with the latest update recorded at 2026‑02‑10T22:00:00+00:00. These values represent a snapshot of ambient conditions captured by the monitoring network; however, air quality can differ across neighborhoods and change throughout the day, so this information may not reflect every location or moment within the city.
