DDDAS Framework for Volcanic Ash Propagation and Hazard Analysis.

摘要

In this paper we will present early work on using a DDDAS based approach to the construction of probabilistic estimates of volcanic ash transport and dispersal. Our primary modeling tools will be a combination of a plume eruption model BENT and the ash transport model PUFF. Data from satellite imagery, observation of vent parameters and windfields will drive our simulations. We will use uncertainty quantification methodology polynomial chaos quadrature in combination with data integration to complete the DDDAS loop.
