What the data includes
The air‑quality record for Chickasaw, Alabama includes three measured pollutants—ozone (O₃), fine particulate matter (PM₂.5) and sulfur dioxide (SO₂)—drawn from a single monitoring location. In total the dataset contains three rows of observations, one for each pollutant.
Ozone is reported as 0.029 ppm at Chickasaw, with its most recent reading dated 2025‑11‑03 16:00 UTC. Fine particles are shown at 4.1 µg/m³, last updated on 2026‑02‑10 23:00 UTC. Sulfur dioxide appears as 0.0004 ppm, also recorded on 2026‑02‑10 23:00 UTC. For each pollutant the minimum, median and maximum values are identical, indicating that only a single measurement is currently available for every compound.
The freshness of the data varies across pollutants. The ozone reading is over a year old, while the PM₂.5 and SO₂ values were captured within the past week, reflecting more recent monitoring for those two substances. Because there is just one station contributing data, coverage is limited to a single point in the city; broader spatial variation cannot be assessed from this set alone. The dataset contains no rows flagged as unknown or missing, but the overall row count (three) underscores that the available information represents a very narrow snapshot of Chickasaw’s air quality at specific moments rather than continuous, city‑wide monitoring.
