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 Corsicana air‑quality record includes data for two common pollutants, ozone (O3) and fine particulate matter (PM2.5). All observations come from a single monitoring site, identified as Corsicana C1051, so the dataset represents one location within the city rather than a network of stations.
For ozone, the only reported value is 0.037 ppm, recorded at 2026‑02‑10 23:00 UTC. The minimum, median and maximum for this pollutant are identical, indicating that just one measurement is available in the current set. Fine particulate matter (PM2.5) shows a single reading of 5.5 µg/m³, logged at 2026‑02‑10 01:00 UTC, again with no variation across minimum, median or maximum.
Both pollutants have been updated within the last seven days, so the data are relatively fresh despite the limited number of observations. Because only one station contributes to the record, there is no spatial spread of measurements across different neighborhoods or micro‑environments in Corsicana. The dataset therefore provides a snapshot rather than a comprehensive picture of city‑wide air quality.
In summary, the available information for Corsicana consists of two pollutant types from one monitoring location, each with a single recent reading and no observed range. While the timestamps are current, the lack of multiple stations or repeated measurements means that conditions can differ elsewhere in the city and at other times.
