What the data includes
The current station data listed for this city is focused on particulate matter (PM). Only one monitoring row is available for Calcasieu Parish, and it reports a single pollutant: PM2.5 measured at 5.8 µg/m³ in Westlake, with the most recent reading timestamped 2026-02-10 23:00 UTC. This observation falls within the “updated within 7 days” freshness category, indicating that the latest data is relatively current, but there are no older or unknown‑age entries for this location.
Because the dataset contains just a single station and a solitary pollutant, the reported range, median and percentile values are all identical at 5.8 µg/m³, showing no variability across measurements. The lack of additional stations means spatial coverage is limited to Westlake, so conditions elsewhere in the parish may differ from what this lone reading captures. No other pollutants such as ozone or nitrogen dioxide appear in the dataset, highlighting an uneven pollutant representation for the area.
