Regional wave forecasts for the Arctic rely on a good understanding of wave propagation through sea ice covers. Disagreements among the models and the lack of field validations cause uncertainty in wave forecasts. A recent viscoelastic ice model has been developed to simulate a wide range of ice covers. This model synthesized several previous models that considered ice covers as a continuum. In this model, a simple parameterization is used to include both energy storage and dissipation mechanisms. However, the model has two parameters, the equivalent elasticity and viscosity, which need to be determined. In this presentation, we will describe the basis of this model, and its calibration using data from a recent field campaign.
