Air quality today

The air quality in Benicia today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 15.0 µg/m³, based on seven valid observations reported through OpenAQ.

Data for this assessment are limited to the available readings and do not include other pollutants such as PM10. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Benicia air‑quality dataset draws from a single monitoring location – the Fitzgerald station – and provides seven pollutant measurements recorded on 2026‑02‑11 00:00 UTC, well within the “updated within 7 days” freshness window. The pollutants available are black carbon (BC), nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), ozone (O₃), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). Because there is only one sensor row per pollutant, the dataset reflects a snapshot rather than a spatial network across the city.

All seven pollutants show identical statistical values because each has a single observation: BC registers 0.51 µg/m³, NO 0.0001 ppm, NO₂ 0.0052 ppm, NOX 0.0054 ppm, O₃ 0.017 ppm, PM2.5 15.0 µg/m³ and SO₂ 0.0014 ppm. Consequently the minimum, median and maximum values are the same for each pollutant, indicating no observed variability in this particular record. The lack of multiple rows means there is no spread or percentile range to describe short‑term fluctuations.

With only one monitoring site, the data give a limited view of Benicia’s overall air quality; conditions can differ across neighborhoods and times of day that are not captured here. Nonetheless, the dataset is fully current as of early February 2026, and it supplies baseline concentrations for each listed pollutant at the Fitzgerald location.

Data notes

The data shown for Benicia reflects seven valid measurements and was updated today (2026‑02‑11T00:00:00+00:00). This snapshot provides a current view of ambient air quality, but conditions can differ across neighborhoods and change throughout the day, so values may not represent every location or moment within the city.
