What the data includes
The dataset for Cobb County, Georgia contains measurements from a single monitoring location – Lowe’s West Cobb – and includes five pollutants: PM1, PM2.5, relative humidity, temperature and UM003 (particles per cubic centimetre). Each pollutant is reported with the same most‑recent timestamp of 2026‑02‑11 01:00 UTC, which falls within the “updated within 7 days” freshness window. Because there is only one row of data, the recorded values represent a snapshot rather than a spatial average across the county.
All five variables show identical minimum, median and maximum figures, indicating that only one observation is available for each. PM1 registers at 9.1665 µg/m³, while PM2.5 measures 20.4222 µg/m³. Relative humidity is recorded at 50.6423 %, temperature at 18.5102 °C and UM003 at 722.7277 particles/cm³. The lack of variation means there is no spread or percentile range to describe typical fluctuations; the single reading serves as both the lower‑ and upper‑bound for each pollutant.
With just one monitoring site, coverage across Cobb County is limited, and conditions can differ in other neighborhoods or at other times of day. The data are recent enough to be considered current, but the singular source means that any assessment of air quality should acknowledge this narrow spatial representation. Users should keep in mind that while the figures are up‑to‑date, they capture only one point in time and location within the county.
