作为耦合模型比对项目第六阶段 (CMIP6) 的一部分，冰盖对海平面变化的影响的预测采用耦合冰盖-气候模型和独立冰盖模型模拟的形式，由 CMIP6 冰盖模型比对项目 (ISMIP6) 监督。本文描述了在 ISMIP6 背景下使用独立格陵兰岛和南极冰盖模型执行的基于过程的海平面变化预测的实验设置。 ISMIP6 协议依赖于一套基于极地大气和海洋 CMIP 的冰盖模型强迫，以探索由于未来排放情景、CMIP 模型、冰盖模型和冰-海洋相互作用参数化而导致的预计海平面变化的不确定性。我们在此描述了定义 ISMIP6 独立冰盖模拟套件所采用的方法，记录了实验框架和实施，并概述了参与冰盖建模小组使用的 ISMIP6 强迫。
Projection of the contribution of ice sheets to sea level change as part of the Coupled Model Intercomparison Project Phase 6 (CMIP6) takes the form of simulations from coupled ice sheet-climate models and stand-alone ice sheet models, overseen by the Ice Sheet Model Intercomparison Project for CMIP6 (ISMIP6). This paper describes the experimental setup for process-based sea level change projections to be performed with stand-alone Greenland and Antarctic ice sheet models in the context of ISMIP6. The ISMIP6 protocol relies on a suite of polar atmospheric and oceanic CMIP-based forcing for ice sheet models, in order to explore the uncertainty in projected sea level change due to future emissions scenarios, CMIP models, ice sheet models, and parameterizations for ice-ocean interactions. We describe here the approach taken for defining the suite of ISMIP6 stand-alone ice sheet simulations, document the experimental framework and implementation, and present an overview of the ISMIP6 forcing to be used by participating ice sheet modeling groups.
