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 OpenAQ feed for Cuernavaca includes eight measured pollutants – carbon monoxide (CO), nitric oxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), ozone (O₃), particulate matter 10 µm or less (PM₁₀), fine particulate matter 2.5 µm or less (PM₂.₅) and sulfur dioxide (SO₂). All of these values come from a single monitoring site, identified as Cuernavaca 01, so the city’s air‑quality picture is based on one station’s observations.
Each pollutant has a single recorded value with identical minimum, median and maximum figures, indicating no variation within the dataset. CO registers at 0.281438888888889 ppm, NO at 0.00053333333333333 ppm, NO₂ at 0.00919555555555556 ppm, NOX at 0.00973111111111111 ppm, O₃ at 0.110322222222222 ppm, PM₁₀ at 60.0 µg/m³, PM₂.₅ at 20.0 µg/m³ and SO₂ at 0.00192452944444444 ppm. Because the most recent timestamp for every pollutant is 2026‑02‑10 22:00 UTC, the data are fresh – updated within three days of today’s date (2026‑02‑13).
The dataset shows a very narrow coverage scope: only one row per pollutant and no historical spread, so it cannot capture temporal fluctuations or spatial differences across Cuernavaca. While the values are current, the lack of multiple stations means conditions may vary in other neighborhoods or at times not reflected here. Users should keep in mind that this snapshot provides a point‑in‑time view from a single location rather than a comprehensive citywide assessment.
