Ice sheet evolution is often described as responses to variation of other climate systems such as atmosphere and ocean, however, it is well known that there is interaction between the systems and the changes in ice-sheet do feedback on the other systems. Therefore development of coupling models, which simulate the climate components simultaneously, is an important subject in order to compute the evolution of ice-sheet with high accuracy. Recently, a second-order conservative regridding schemes is developed to effectively transfer the climate model field such as snow accumulation to ice-sheet model. In the present study, the peformance of the library will be presented in terms of numerical efficiency. Also, impact on ice-sheet model simulation by difference in the regridding order will be evaluated.
