　　Coupler is a fundamental software tool for earth system modelling.Targeting the requirements of 3-D coupling,high-level sharing,common model software platform and better parallel performance,we started to design and develop a community coupler (C-Coupler) from 2010 in China,and finished the first version (C-Coupler1) recently.The C-Coupler1 is a parallel 3-D coupler that achieves the same (bit- identical) result with any number of processes.Guided by the general design of the C- Coupler,the C-Coupler1 enables various component models and various coupled model versions to be integrated on the same common model software platform to achieve a higher-level sharing,where the component models and the coupler can keep the same code version in various model versions for simulation.Moreover,it provides the C-Coupler platform,a uniform runtime environment for operating various kinds of model simulations in the same manner.Now the C-Coupler1 is ready for earth system modelling,and it is publicly available.In China,there are more and more model groups using the C-Coupler1 for the development and application of models.
