Assimilation in a moving mesh framework
A conservation-based moving mesh method is applied to a shallow ice model of a glacier that incorporates ice diffusion and the net ice-equivalent accumulation/ablation. The numerics of this moving mesh approach are demonstrated, along with how assimilation of measured data can be used within the moving framework to improve the prediction of ice sheet movement. Comparisons with the EISMINT test scenario are shown to demonstrate how this approach performs.
