Air quality today

The air quality today in Apodaca is rated as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 18.0 and a PM10 reference value of 37.0, based on five valid observations.

Data is shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Apodaca’s air‑quality feed consists of a single monitoring station that records eight pollutants: carbon monoxide (CO), nitrogen 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). The most recent data points are from 2026‑02‑10 22:00 UTC for CO, O₃, PM₁₀, PM₂.₅ and SO₂, while the nitrogen‑oxide series (NO, NO₂, NOX) were last updated on 2026‑01‑13 14:00 UTC, making those three values over a month older than the rest.

All eight measurements are single‑value entries; each pollutant shows identical minimum, median and maximum readings, indicating that only one observation is currently available per compound. CO registers at 1.12 ppm, O₃ at 0.042 ppm, PM₁₀ at 37 µg/m³ and PM₂.₅ at 18 µg/m³, while the nitrogen oxides are all below 0.03 ppm (NO 0.0166 ppm, NO₂ 0.0077 ppm, NOX 0.028 ppm). Sulfur dioxide is measured at 0.0045 ppm.

Because the dataset contains just one row per pollutant, there is no spread or variability to describe; the reported values represent the sole snapshot captured for each substance. The freshness of the data is uneven: half of the pollutants have been refreshed within the last three days, whereas the nitrogen‑oxide trio remains “old” by more than a month. Consequently, while the station provides coverage of the full pollutant suite, the limited number of observations and the age disparity mean that the picture of air quality in Apodaca is based on isolated moments rather than continuous monitoring, and conditions can differ across locations and times not captured here.

Data notes

The data shown for Apodaca are based on five valid measurements and have been refreshed recently, with the latest update recorded at 2026‑02‑10T22:00:00+00:00 (updated within 3 days). This snapshot reflects conditions at the time of collection; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
