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 current station data listed for this city is focused on particulate matter (PM). Only one monitoring location contributes to the dataset, reporting a PM2.5 concentration of 26.0 µg/m³ measured at Williams Middle School. The most recent reading was recorded on 2026-02-10 23:00 UTC, which falls within the “updated within 7 days” freshness category, indicating that the available data is relatively current for this pollutant.
Because there is a single row of data, the reported values show no statistical spread: the minimum, median, maximum, 10th percentile and 90th percentile are all identical at 26.0 µg/m³. This lack of variability means the dataset cannot illustrate fluctuations over time or across different parts of Florence, South Carolina. Consequently, while the measurement is fresh, the overall coverage is limited to one site and one pollutant, so city‑wide air quality conditions may differ from what this single point reflects.
