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 PM2.5 measurements are available from a single monitoring site located on Aberdeen‑Division St. The dataset contains one row, and the most recent reading was recorded at 2026‑02‑10 23:00 UTC, which falls within the “updated within 7 days” freshness category.
Because there is just one station, the reported values are identical across statistical summaries: the minimum, median, maximum, 10th percentile and 90th percentile all equal 1.2 µg/m³. This means the observed range is effectively zero, offering no insight into variability across the city. The limited coverage implies that conditions elsewhere in Aberdeen may differ from what this single point measurement shows, and the dataset does not include any older or unknown‑timestamp entries. Consequently, while the data are recent, they provide a very narrow snapshot rather than a comprehensive picture of air quality throughout the area.

Data notes
The data shown reflects three valid measurements and is updated within 3 days, with the most recent reading recorded on 2026‑02‑10 at 23:00 UTC. This snapshot represents conditions at a single point in time and may not capture variations across different neighborhoods or times of day within Aberdeen, Washington. Consequently, actual air quality can differ locally and change rapidly throughout the city.
