Air quality today

The air quality in Birmingham, Alabama is currently classified as Good. The primary pollutant measured today is fine particulate matter (PM2.5). Among the valid observations, the average PM2.5 concentration is 6.0 µg/m³ and the corresponding PM10 level is 19.0 µg/m³, based on 41 valid measurements recorded by OpenAQ.

These values reflect the conditions at the time of sampling and are presented for informational purposes only. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Birmingham, Alabama air‑quality dataset currently contains three measured pollutants – ozone (O₃), fine particulate matter (PM₂.5) and coarse particulate matter (PM₁₀). All data come from three monitoring stations, each providing a single recent row for every pollutant that is reported. The most recent observations were all recorded on 2026‑02‑10 at 23:00 UTC, so the freshest values are less than two weeks old and fall within the “updated within 7 days” freshness category.

For PM₁₀ the three stations report concentrations ranging from a low of 11.0 µg/m³ to a high of 19.0 µg/m³, with a median value of 14.0 µg/m³. The extreme reading of 19.0 µg/m³ comes from the NO. BHAM site. PM₂.5 shows a tighter spread: values run from 5.7 to 8.3 µg/m³, median 6.0 µg/m³, and the lowest measurement (5.7 µg/m³) was recorded at WYLAM. Ozone concentrations are expressed in parts per million; they vary between 0.005 ppm and 0.037 ppm, with a median of about 0.021 ppm. The maximum ozone value of 0.037 ppm also originates from the NO. BHAM monitor.

Because each pollutant is represented by only three stations, spatial coverage across Birmingham is limited; some neighborhoods may not be directly sampled. Nevertheless, all rows are recent, so the dataset reflects conditions that were current as of early February 2026 rather than historical or outdated measurements. The range between minimum and maximum values differs noticeably among pollutants – PM₁₀ shows a broader spread than PM₂.5, while ozone sits in an intermediate range – indicating that variability can depend on both pollutant type and the specific monitoring location.
