What the data includes
The Alachua County air‑quality dataset currently includes two measured pollutants – ozone (O3) and fine particulate matter (PM2.5). Data come from four individual rows representing two monitoring stations, with each pollutant recorded at both sites. The most recent readings for both O3 and PM2.5 were logged on 2026-02-11 00:00 UTC, and the dataset notes that these values have been updated within the past seven days, indicating relatively fresh coverage for the area.
Ozone concentrations in the county range from a low of 0.036 ppm to a high of 0.044 ppm, with a median value of about 0.040 ppm. The spread is modest; the 10th percentile sits at roughly 0.037 ppm and the 90th percentile near 0.043 ppm, suggesting that most measurements cluster tightly around the middle of the observed range. Fine particulate matter shows a broader distribution: values fall between 3.3 µg/m³ and 5.2 µg/m³, with a median of 4.25 µg/m³. Here the 10th percentile is about 3.49 µg/m³ and the 90th percentile reaches roughly 5.01 µg/m³, indicating more variability in PM2.5 levels across the two stations.
Both pollutants are reported from the same location – Paynes Prairie Farm – which means spatial coverage within Alachua County is limited to this single site. While the timestamps are recent, the dataset’s narrow geographic footprint and small number of rows mean that conditions elsewhere in the county may differ from what is captured here. Users should keep in mind that these figures reflect only a snapshot from one monitoring point rather than a comprehensive city‑wide picture.

Data notes
The data shown for Alachua County reflects two valid measurements and was updated today (2026‑02‑11T00:00:00+00:00). While this snapshot provides a current view of ambient conditions, air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment within the county.
