Comparison of seasonal sea-ice model results with satellite microwave data in the Weddell Sea

Sea-ice simulations are generated with a dynamic-thermodynamic coupled ice-ocean model in the Weddell Sea, Antarctica, for a period in 1992. The model output is compared with detailed measurements made at a drifting ice camp, and with ice kinematics measurements made by ERS-1. Results indicate that the model reproduces Eulerian drift velocity at ISW-1 relatively well during the early drift period, provided rheological parameters (e.g. ice strength P*) are scaled correctly. Deviations of velocity components from observed values along a Lagrangian drift trajectory also require parameter adjustments to achieve correspondence.
