The Hawai‘i Island Air Quality (HIAQ) network is a planned state-of-the-art network of air quality sensors to be located around Hawai‘i Island, in order to provide community members, educators, and researchers with access to measurements of local air quality in real time. Hawaiian air quality is affected by the Kilauea Volcano, which emits high levels of sulfur dioxide (SO2), a major air pollutant. The resulting “volcanic smog” (“vog”), a mixture of SO2 and fine particulate matter (PM), can have negative impacts on human health as well as agriculture.
Local air quality, and the impacts of vog, are currently measured by the Hawai‘i Deparment of Health (click here for data) as well as the National Park Service and United States Geologic Survey (click here for data). However, because of the high variability of the volcanic plume, residents’ exposures to vog cannot currently be estimated easily. This is the major goal of the HIAQ network, which will make real-time measurements at much more local scales, involving about 40 sensor nodes located around the island.
