Air quality today
The air quality in Bryson City today is classified as Good. The primary pollutant measured is PM2.5 (fine particles), with a reported concentration of 5.0 µg/m³. This assessment is based on a single valid measurement recorded by OpenAQ.
No other pollutants reached reporting thresholds, and the data reflects the conditions at the time of collection. 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
Bryson City’s air‑quality feed includes measurements for ozone (O₃) and fine particulate matter (PM₂.5). The dataset comprises four individual observation rows drawn from a single monitoring site, with one row each for O₃ and PM₂.5 that are recent enough to be considered current, while the remaining three rows are older than 30 days.
The ozone record shows values ranging from 0.016 ppm at the low end to 0.041 ppm at the high end, with a median of 0.0285 ppm. The interdecile spread (10th to 90th percentile) runs from about 0.0185 ppm up to 0.0385 ppm, indicating modest variability within the limited recent sample. This ozone entry was last refreshed on 2025‑11‑03 13:00 UTC and is flagged as “Old data,” reflecting that it may not represent present conditions.
Fine particulate matter (PM₂.5) readings span from 5.0 µg/m³ to 7.0 µg/m³, with a median of 6.0 µg/m³. The 10th and 90th percentiles are 5.2 µg/m³ and 6.8 µg/m³ respectively, suggesting a relatively tight distribution among the recent observations. This PM₂.5 record was updated most recently on 2026‑02‑11 00:00 UTC and is marked as “Updated within 7 days,” making it the freshest data point available for Bryson City.
Overall, the city’s air‑quality profile is based on a very small number of measurement rows, with only one recent entry per pollutant. The majority of the dataset consists of older observations, so while the listed ranges give an idea of recent conditions, actual concentrations can differ across locations and times within Bryson City.
