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.
DISCLAIMER: The Mountain View monitoring station was taken out of service in August 2016 by Hawaii Department of Health for maintanence reasons. The data feed for the aerosol observations was disrupted at the University of Hawaii at Manoa during a system failure. We are working to bring this data back online soon. In the meanwhile, information can be accessed through a variety of websites such as the Hawaii Department of Health or AIRNOW.gov.
Disclaimer: The above data shown reflect the current values only, as available from the individual data providers.
