抽象。冰川和冰帽目前对海平面上升的贡献最大。因此，模拟主要冰盖的动态和质量平衡是一个重要的问题，以调查当前的状态和未来的反应，对不断变化的环境条件，即全球变暖的冰冻圈。这就需要一个功能强大、易于使用、多功能的多近似冰动力学模型。在Pattyn（2003）的冰盖模型基础上发展了模块化的多近似热力学冰模型RIMBAY，并在此基础上改进了原有模型，如引入了浅冰-浅冰架耦合器和基于Schoof（2007）启发式分析方法的全三维地线迁移方案。我们总结了完整的斯托克斯方程和在这个模型中实现的几个近似，我们描述了不同的数值离散。结果是交叉验证对以前的出版物处理冰建模，和一些额外的人工设置证明了不同的求解器和它们的内部耦合的鲁棒性。RIMBAY的设计是为了轻松适应新的科学问题。因此，我们在非常不同的设置中展示了RIMBAY在地球系统科学中的适用性和功能，特别是冰建模。
Abstract. Glaciers and ice caps exhibit currently the largest cryospheric contributions to sea level rise. Modelling the dynamics and mass balance of the major ice sheets is therefore an important issue to investigate the current state and the future response of the cryosphere in response to changing environmental conditions, namely global warming. This requires a powerful, easy-to-use, versatile multi-approximation ice dynamics model. Based on the well-known and established ice sheet model of Pattyn (2003) we develop the modular multi-approximation thermomechanic ice model RIMBAY, in which we improve the original version in several aspects like a shallow ice–shallow shelf coupler and a full 3D-grounding-line migration scheme based on Schoof's (2007) heuristic analytical approach. We summarise the full Stokes equations and several approximations implemented within this model and we describe the different numerical discretisations. The results are cross-validated against previous publications dealing with ice modelling, and some additional artificial set-ups demonstrate the robustness of the different solvers and their internal coupling. RIMBAY is designed for an easy adaption to new scientific issues. Hence, we demonstrate in very different set-ups the applicability and functionality of RIMBAY in Earth system science in general and ice modelling in particular.
