Air quality today

The air quality in Guadalupe, Nuevo León is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 14.56 µg/m³ and a PM10 level of 70.0 µg/m³ based on eight valid observations.

Data are displayed via OpenAQ, reflecting the latest available readings for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Guadalupe air‑quality record draws on 19 data rows collected from two monitoring sites, each reporting a set of eight common 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 most recent observations were logged on 2026‑02‑10 at 22:00 UTC, so the dataset reflects conditions that are less than a week old for every pollutant.

Across the rows, ozone peaks at 0.054 ppm while its median value sits near 0.023 ppm, indicating a modest spread between low‑end (0.019 ppm) and high‑end readings. Particulate matter shows a broader range: PM₁₀ varies from 20 to 70 µg/m³ with a median of 43 µg/m³, and PM₂.₅ spans 0 to 31.8 µg/m³, centering around 14.6 µg/m³. Carbon monoxide is tightly clustered between 1.53 and 1.59 ppm (median 1.56 ppm). The nitrogen‑oxide family remains low‑level throughout the period, with NO ranging from 0.0031 to 0.0053 ppm (median 0.0042 ppm), NO₂ from 0.0131 to 0.0136 ppm (median 0.01335 ppm) and NOX from 0.0166 to 0.0182 ppm (median 0.0174 ppm). Sulfur dioxide is similarly constrained, moving between 0.0039 and 0.0044 ppm (median 0.00415 ppm).

Because the two stations supply all eight pollutants, coverage is comprehensive in terms of chemical species but limited geographically; variations across the city may not be captured fully by just these locations. The data are uniformly recent, yet the modest number of rows means that short‑term spikes or localized events could be underrepresented. Users should keep in mind that the reported ranges reflect the specific sampling points and time window represented here.
