Air quality today
The air quality in Baton Rouge today is classified as Good. The primary pollutant identified is PM2.5 (fine particles), with a measured concentration of 5.3 µg/m³ based on two valid observations reported through OpenAQ.
No other pollutants reached reporting thresholds, and the data set includes only these two measurements for the current period. 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
The Baton Rouge air‑quality data set includes measurements for ozone (O₃) and fine particulate matter (PM₂.5). Both pollutants are reported from a single monitoring location identified as “Capitol,” giving a total of two data rows—one for each pollutant. The most recent readings were recorded on 2026-02-10 at 23:00 UTC, which falls within the past seven days and represents the freshest information available for this city.
For ozone, the only value captured is 0.042 ppm, which also serves as the minimum, median, and maximum across the dataset, indicating no observed variation in the limited sample. The PM₂.5 measurement shows a single reading of 5.3 µg/m³, again acting as the sole statistic for that pollutant with identical minimum, median, and maximum values. Because each pollutant has just one data point, there is no spread to describe; the reported figures represent both typical and extreme conditions at the Capitol site during the last update.
The coverage in Baton Rouge is therefore narrow: only one monitoring station contributes data, and each pollutant is represented by a single observation. While the timestamps are recent, the lack of multiple stations or repeated measurements means the dataset cannot capture spatial differences across the city or temporal fluctuations beyond the recorded moment. Users should keep in mind that air‑quality conditions can change throughout Baton Rouge, and the current figures reflect only the specific time and place of the Capitol sensor.

Data notes
The data shown for Baton Rouge reflects two valid measurements and was updated within three days, with the most recent reading recorded at 2026‑02‑10T23:00:00+00:00. This snapshot provides a brief view of current conditions; however, air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
