Abstract
A coupler is software that couples each component model composing a huge, complex simulation model such as climate model. In this study, an atmospheric model and an aerosol model, which are component models of climate model MIROC, are coupled by a model coupler Jcup to evaluate its performance of three-dimensional data exchange. Comparisons of various data exchange strategies have revealed that data buffering is the main bottleneck of the coupling process. Our results suggest the direct data exchange is superior to other coupling strategies in exchange of three-dimensional data in atmospheric and aerosol models.
