Abstract. Reliable numerical simulation plays a critical role in climate change study. The reliability includes the technical reproducibility, i.e. bit-identical results of numerical simulation can be reproduced. It is very important for model development and scientific researches but has not been satisfactorily addressed yet so far. To address the technical reproducibility, necessary information about it is firstly analyzed, and how to enhance it on the Community Coupler (C-Coupler) platform, a uniform runtime environment that can operate various kinds of model simulations in the same manner, is then detailed. Moreover, we share a series of experiences and suggestions with scientists and model groups for achieving the technical reproducibility. We believe that, the proposed implementations, experiences and suggestions can be easily extended to other model platforms, and can prospectively advance model development and scientific researches in future.
