What the data includes
The Anderson air‑quality dataset currently contains measurements for two pollutants: ozone (O3) and fine particulate matter (PM2.5). Both are reported from a single monitoring location, identified as Anderson‑Eastside El, which appears in two rows of data for each pollutant. Overall the city’s record includes four rows; two of those were updated within the past seven days, while the remaining two are older entries.
For ozone, the most recent reading is 0.033 ppm recorded at Anderson‑Eastside El on 2026‑02‑10 23:00 UTC. Across all available O3 observations the values range from a low of 0.033 ppm to a high of 0.049 ppm, with a median of 0.041 ppm. The 10th percentile sits at 0.0346 ppm and the 90th percentile at 0.0474 ppm, indicating that most recent measurements cluster within a relatively narrow band.
PM2.5 shows its latest value at 21.7 µg/m³ from the same site and timestamp (2026‑02‑10 23:00 UTC). The particulate data span from 2.7 µg/m³ up to 21.7 µg/m³, with a median of 12.2 µg/m³. The lower decile is 4.6 µg/m³ and the upper decile reaches 19.8 µg/m³, revealing a broader spread compared with ozone.
Because only one monitoring station contributes data, spatial coverage across Anderson is limited; conditions can differ in other neighborhoods that are not captured here. Additionally, half of the rows are older than seven days, so while some recent measurements exist, the dataset does not provide continuous, city‑wide monitoring at this time.
