attribute NC_GLOBAL summary String The Vog Measurement and Prediction Project (VMAP) provides twice-daily forecasts of vog (volcanic smog) for the region surrounding the main Hawaiian islands at approximately 1-km resolution. Generated using the HYbrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) numerical dispersion model, VMAP uses estimates of volcano emissions along with forecast winds to predict the concentrations of sulfur dioxide gas (SO2) and sulfate aerosol particles (SO4) averaged over the lowest 100-m of the atmosphere downwind of the ongoing Kilauea eruption on Hawaii Island. Wind fields and thermodynamic forecast data produced by the Mauna Kea Weather Center (MKWC) from the state-of-the-art Weather Research and Forecast (Weather Research and Forecasting Model (WRF)) model, with a statewide resolution of 4.5 km, provide input for the HYSPLIT model. A combination of remote sensing and in situ observations are used to provide initial conditions regarding volcanic emissions and to validate the model simulations. Vog is a form of air pollution that results from volcanic emissions that is primarily a mixture of SO2 gas and SO4 aerosol. SO2 (invisible) reacts with oxygen and moisture in the air to produce SO4 aerosol (visible). SO2 is expected to be the main problem in areas near the vent (Hawaii Volcanoes National Park) while SO4 aerosol is expected to be the main problem at locations far from the vent (Kona and farther north and west).
