UH faculty launches first-ever online ‘vog’ forecast H ERTHA AUMOEUALOGO News Editor
A closer look at updated forecasts of volcanic smog, or vog, is now available at your fi ngertips, thanks to the efforts of University of Hawai‘i researchers. Steven Businger, the principal investigator of the Vog Measurement and Prediction Project, said via e-mail, “The model maps show the extent of the vog, they are quite accurate.” For three years, Businger and other researchers have been working to increase public awareness through the website. So far, he said, “people who are sensitive to vog (e.g., get allergic reactions) have been quite vocal in their approval of the site.” When questioned about the beginning of the program, Roy Huff, the lead weather and vog modeler for the website wrote, “The initial template was created by a couple of employees within the department, and I received assistance with graphical output of the meteograms and scatter plots from MS candidate Doug Stolz.” Vog is defined on the VMAP home page as “a mixture of sulfur dioxide (SO2) gas and sulfate (SO4) aerosol. SO2 (invisible) reacts with oxygen and moisture in the air to produce SO4 aerosol (visible).” This has the potential to become a health problem for people with asthma and other respiratory complications. Some of the project’s funding comes

Volcanic emissions from Kīlauea make their way down the island chain in the form of vog. from the United States Geological Survey, a federal agency which studies the landscape of the U.S. The sulfur dioxide and sulfate measurements on the VMAP website are provided by the Hawai‘i State Department of Health and the National Park Service. Many Hawai‘i residents have been exposed to vog, claiming it smells like the smoke of burning rubber tires. Physical reactions include irritated eyes, sore throat and burning sinuses. The endless discharge of volcanic gases, in this case sulfur dioxide from Kīlauea’s erupting vents, also causes rainwater to become contaminated with acid, which presents a health hazard. The website not only provides a reliable prediction of vog, but also serves a

larger purpose in House Bill 314, which relates to disaster awareness. A Disaster Preparedness Commission will be established in developing safety plans for natural hazards and emergencies. Although the bill will not be effective for another nine years, UH has taken the initiative. According to Businger, one of the problems of predicting vog is underestimating sulfate aerosol, specifically on the Kona side of the Big Island. “We hope to implement clouds in our dispersion model this spring and that should improve the forecasts,” he said. “Since the original source area is small, minor errors in wind direction can result in large errors in vog forecasts.” “The project is in cooperation with the USGS, and funding is currently slated to

expire Sept. 30 of this year,” said Huff in an e-mail, “We are currently looking for additional sources of funding.” However, there are currently two main updates in the near future which should improve the accuracy of the model displayed on the webpages. First, plume height algorithms that will better determine exactly where within the atmosphere pollutants are being dispersed. Secondly, a wet deposition algurithm to deal with sulfate conversion rates within the clouds. UH researchers monitor the vog to provide the most reliable information and updates on Kīlauea’s recent activity. While the website’s core purpose has already been laid out, there is still a lot of work to be done. For more information, visit http://weather.hawaii.edu/vmap.
