Summary: | Amethod is presented for an evaluation of coupled dynamic and thermodynamic ice models using the RADARSAT Geophysical Processor System (RGPS) data and prod-ucts for validation. The technique has been applied to a standard viscous-plastic rhe-ology with a simple two-level ice thickness model for three test regions of the Arctic pack ice. High correlation is obtained between observed and predicted ice speeds. The model predictions show reasonable correlation with the data when examining shear and vorticity, but poorer correlation with divergence. The amount of opening is under pre-dicted in these simulations. |
