What the data includes

The current station data listed for this city is focused on particulate matter (PM). In Newport, Washington the OpenAQ feed provides seven rows of observations from two monitoring sites, all reporting PM2.5 concentrations measured in micrograms per cubic metre. The most recent timestamp across the dataset is 2024-07-08 13:00 UTC, so the freshest reading is just a few days old, while the remaining six entries are classified as older data.

PM2.5 values span a very wide range, from a minimum of –3 µg/m³ up to a maximum of 288 µg/m³, with the median sitting at 0 µg/m³ and the 90th percentile around 122 µg/m³. A typical recent measurement recorded at the Newport‑Calispel site was 10.2 µg/m³ on the latest update. Because only two stations contribute data, spatial coverage is limited and the dataset contains a mix of very low, zero or even negative values alongside occasional high spikes, indicating that air quality can differ markedly across locations and times within the city.
