Volcanic ash modeling for North Pacific volcanoes automated operational monitoring and virtual globes 4277

There are over 100 active volcanoes in the North Pacific (NOPAC) region, most of which are located in uninhabited areas. The Alaska Volcano Observatory (AVO) operationally monitors these volcanoes and is a joint program of the United States Geological Survey, the Geophysical Institute of the University of Alaska Fairbanks and the State of Alaska Division of Geological and Geophysical Surveys. Dispersion models play a pivotal role in forecasting the movement of volcanic ash clouds by complementing remote sensing data and visual observations from the ground and aircraft. Puff is a three dimensional dispersion model primarily designed for forecasting volcanic ash dispersion and is used by AVO and other agencies.
