摘要。可靠的数值模拟在气候变化研究中起着关键作用。可靠性包括位相同再现性，即数值模拟的位相同结果能够再现。它对地球系统建模非常重要，已经在建模组内部用于模型开发。然而，很少在更广泛的范围内甚至在世界范围内考虑它。为了帮助实现世界范围内的位相同再现性，我们介绍了在Community Coupler （C-Coupler）平台上的位相同再现性的详细实现，Community Coupler是一个统一的运行时软件环境，以相同的方式配置、构建和运行模型。此外，我们还分享了关于位相同再现性的一系列经验和建议。我们相信这些实现、经验和建议可以很容易地推广到其他模型软件平台，并对未来的模型开发和科学研究具有前瞻性的推动作用。
Abstract. Reliable numerical simulation plays a critical role in climate change study. The reliability includes bitwise identical reproducibility, i.e. bitwise identical result of numerical simulation can be reproduced. It is important to Earth system modeling and has already been used intra modeling groups for the model development. However, it is rarely considered in a wider range even worldwide. To help achieve the worldwide bitwise identical reproducibility, we introduce the detailed implementations for the bitwise identical reproducibility on the Community Coupler (C-Coupler) platform, a uniform runtime software environment that configures, builds and runs the models in the same manner. Moreover, we share a series of experiences and suggestions regarding the bitwise identical reproducibility. We believe that these implementations, experiences and suggestions can be easily extended to other model software platforms and can prospectively advance the model development and scientific researches in the future.
