Air quality today

The air quality in Brigham City, Utah is rated as Good today. The primary pollutant measured is PM2.5 (fine particles), with a reported concentration of 3.2 µg/m³. Five valid measurements were used to determine this assessment, and no PM10 value is available.

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

What the data includes

The Brigham City air‑quality dataset currently includes five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), ozone (O₃) and fine particulate matter (PM₂.5). Data come from two monitoring stations that together contributed eight individual rows of observations. All of the most recent values were recorded on 2026‑02‑11 at 00:00 UTC, so every pollutant in this set has a fresh timestamp within the last seven days.

Across the five compounds the observed concentrations span modest ranges. NO₂ varies from a low of 0.0056 ppm to a high of 0.013 ppm, with a median around 0.0093 ppm; O₃ shows a broader spread, ranging between 0.015 ppm and 0.034 ppm and centering near 0.0245 ppm. PM₂.5 values are measured in micrograms per cubic metre, from 3.2 µg/m³ up to 10.9 µg/m³ with a median of about 7.05 µg/m³. The nitrogen monoxide reading is constant at 0.001 ppm and the NOX value is fixed at 0.0067 ppm for the single row that reports each, indicating limited variability for those two gases in this snapshot.

The dataset’s coverage is uneven: while NO₂, O₃ and PM₂.5 each have multiple rows (two stations reporting two rows each), NO and NOX are represented by only one row each. This means the picture of nitrogen monoxide and total nitrogen oxides is based on a single measurement point, whereas ozone and particulate matter benefit from broader sampling across both stations. Overall, the data are recent but the limited number of rows for some pollutants suggests that city‑wide conditions could differ in places or times not captured by these specific observations.
