SEALION overall objectives and goals
The aim of this project is to assess and improve the performance of
coupled global atmosphere-sea ice-ocean models (AOGCMs) in reproducing
sea ice in the high southern latitudes. This will be achieved by (1)
deriving data sets of sea ice con centration and motion using remote
sensing techniques, (2) performing selected runs with a sophisticated
high-resolution dynamic-thermodynamic sea ice model, which will be optimized
with the data sets derived within this project, and (3) ana lyzing the
output of coupled global AOGCM runs. An improved parameterization of
the thermodynamic and dynamic processes for the Southern Ocean sea ice
is only feasible with improved sea ice concentration and velocity data.
Therefore, the objectives of this proposal are
-
to develop data sets (time series) of ice drift
and concentration for the SMMR and SSM/I period (1978-1999)
(Remote Sensing Part) and
-
to derive an optimized dynamic-thermodynamic sea
ice model for the use in coupled atmosphere-ocean general circulation
models for climate research (Mod elling Part).
