Air quality today
The air quality today in Tlalnepantla is classified as USG. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 38.0 and a PM10 reference value of 45.0, based on eight valid observations collected via OpenAQ.
These figures reflect the current monitoring results for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The dataset for Tlalnepantla pulls information from a single monitoring station that contributes 14 recent rows of data across eight pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), ozone (O₃), particulate matter 10 µm (PM₁₀), particulate matter 2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). All of the measurements have been refreshed within the past week, with the most recent timestamps recorded on 2026‑02‑10 22:00 UTC for CO, NO₂, O₃, SO₂, NO and NOX, and on 2026‑02‑09 23:00 UTC for PM₁₀ and PM₂.₅.
Across the eight gases, the observed values span modest ranges. CO varies from a low of 0.4 ppm to a high of 0.7 ppm, while NO₂ sits between 0.027 ppm and 0.037 ppm. Ozone shows the widest spread, ranging from 0.01 ppm up to 0.123 ppm. Particulate matter concentrations are also diverse: PM₁₀ ranges from 18 µg/m³ to 45 µg/m³ and PM₂.₅ from 10 µg/m³ to 38 µg/m³, with median values of 31.5 µg/m³ and 24 µg/m³ respectively. SO₂ is consistently low, recorded between 0.003 ppm and 0.004 ppm, and the nitrogen oxides are stable at a single reported value of 0.042 ppm for NOX and 0.005 ppm for NO.
Because only one station supplies data, spatial coverage within the city is limited; conditions can differ in neighborhoods that lie farther from this monitoring point. Nevertheless, the dataset offers a recent snapshot of air quality, with most pollutants captured at least to the tenth percentile (e.g., CO p10 ≈ 0.43 ppm, PM₁₀ p90 ≈ 42.3 µg/m³), allowing users to see typical versus extreme readings for Tlalnepantla during the last seven days.
