This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality in Carbon County, Utah is classified as Good today. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 2.0 µg/m³ based on five valid readings collected through OpenAQ.
Overall conditions meet the criteria for a Good rating, with no additional pollutants reported at measurable levels. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
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
Carbon County’s OpenAQ feed contains data for six pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), combined nitrogen oxides (NOX), ozone (O₃), particulate matter 10 µm or smaller (PM10) and particulate matter 2.5 µm or smaller (PM2.5). All of these measurements come from a single monitoring station, so the dataset represents one row per pollutant.
The most recent observations for NO, NO₂, NOX, O₃ and PM2.5 were all recorded on 2026‑02‑10 at 23:00 UTC, meaning the data are fresh within the last seven days. In contrast, the PM10 reading is older, dated 2022‑05‑06 at 15:00 UTC, and is flagged as “Old data.” Because only one station contributes, there is no spatial spread of values across the county; any variation in air quality throughout Carbon County cannot be captured by this dataset.
Across the five recent pollutants the reported concentrations are identical to their median values, showing no observed range: NO sits at 0.0003 ppm, NO₂ at 0.0022 ppm, NOX at 0.0025 ppm, O₃ at 0.048 ppm and PM2.5 at 2.0 µg/m³. The lack of minimum‑maximum spread indicates that only a single measurement is available for each, rather than a series of readings over time. PM10, while having a single value of 23.0 µg/m³, is also limited to one data point and is considerably older.
Overall the dataset provides a snapshot of six pollutants from one location, with most values updated within the past week but one key particulate metric dating back several years. Consequently, while the numbers give a basic picture of current conditions at that specific site, they do not reflect broader temporal or geographic variations across Carbon County.

Data notes
The current dataset for Carbon County includes five valid measurements and was updated within three days, with the most recent reading recorded on 2026‑02‑10 at 23:00 UTC. These values reflect conditions captured at specific monitoring sites and times; air quality can vary across different neighborhoods and throughout the day, so this snapshot may not represent every location or moment in the city.
