Remobilized volcanic ash from ground deposits can present significant hazards to human health, infrastructure, and aviation. Modeling ash remobilization events is an important tool that can provide information on timing and magnitude to assist in planning and response. We investigate how the horizontal resolution of meteorological data, specifically that of friction velocity provided by Numerical Weather Prediction (NWP) models, affects the estimated vertical mass flux and modeled concentrations of volcanic ash. We then apply a method designed to reduce
