The observed conditions at the stations listed in the table below are actual conditions measured by Hawaii State Department of Health and National Park Service. These values are not modeled predictions. In the case of the aerosol measurements, PM2.5 (Particulate Matter of size 2.5 µm or less) observed values include SO4 as well as all other aerosols smaller than 2.5 microns. PM2.5 may include dust, salts, and other pollutants. More information and observations can be found on the Hawaii State Department of Health website here.
