Abstract
The baseline performance of the latest version (version 2) of an intermediate resolution, stand-alone
climate oceanic general circulation model, called LASG/IAP (State Key Laboratory of Numerical Modeling
for Atmospheric Sciences and Geophysical Fluid Dynamics/Institute of Atmospheric Physics) Climate system
Ocean Model (LICOM), has been evaluated against the observation by using the main metrics from Griffies
et al. in 2009. In general, the errors of LICOM2 in the water properties and in the circulation are comparable
with the models of Coordinated Ocean-ice Reference Experiments (COREs). Some common biases are still
evident in the present version, such as the cold bias in the eastern Pacific cold tongue, the warm biases off
the east coast of the basins, the weak poleward heat transport in the Atlantic, and the relatively large biases
in the Arctic Ocean. A unique systematic bias occurs in LICOM2 over the Southern Ocean, compared with
CORE models. It seems that this bias may be related to the sea ice process around the Antarctic continent.
