| Zusammenfassung |
| We present the results of the first ice sheet model intercomparison project
for higher-order and full-Stokes ice sheet models. These models are compared
and verified in a series of six experiments of which one has an analytical
solution obtained from a perturbation analysis. The experiments are applied
to both 2-D and 3-D geometries; five experiments are steady-state diagnostic,
and one has a time-dependent prognostic solution. All participating models
give results that are in close agreement. A clear distinction can be made
between higher-order models and those that solve the full system of
equations. The full-Stokes models show a much smaller spread, hence are in
better agreement with one another and with the analytical solution. |
