利用Griffies等人在2009年提出的主要指标，对LASG/IAP（大气科学与地球物理流体动力学数值模拟国家重点实验室/大气物理研究所）气候系统海洋模式（LICOM）的最新版本（第2版）的基线性能进行了评估。一般而言，LICOM 2在水的属性和在环流的误差是可比的协调海洋-冰参考实验（COREs）模式。一些常见的偏差在当前版本中仍然很明显，例如东太平洋冷舌的冷偏差，盆地东海岸的暖偏差，大西洋的弱向极热输送，以及北冰洋相对较大的偏差。与CORE模式相比，LICOM 2在南大洋上出现了独特的系统偏差。看来这种偏差可能与南极大陆周围的海冰过程有关。
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.
