The objectives are improve the land surface model and the surface and sub-surface processes in the ocean model.
The models are used in the unified global atomosphere and ocean coupled model. We improve the fluxes between atmosphere and land surface, and between atmosphere and ocean.
- To decrese the bias which snow melting season is too early,
we improve the snow processes.
- To correct the deficit which the ratio of river runoff is too small, we improve the soil processes.
- To improve the simulation of oceanic seasonal and interannual
variations, we verify heat flux obtained in modeling
of ocean surface processes and tune ocean mixed layer scheme.
- To reduce the biases of fluxes in the coupled model, we investigate and tune the fluxes at sea surface in the atmospheric model.
