Next Generation Climate Change Experiments Needed to Advance Knowledge and for Assessment of CMIP6; Aspen, Colorado; August 4-9, 2013

这些资金支持由阿斯彭全球变化研究所组织的题为“下一代气候变化实验需要促进知识和评估CMIP6”的研讨会。随着政府间气候变化专门委员会（IPCC）第五次评估报告（IPCC AR5）进程接近尾声，以及耦合模式比对项目（CMIP5）广泛的模式比对工作达到高潮，科学认识上出现的差距为新的气候模式实验带来了机会，这些实验探索了通过一套协调的模式实验最能解决的科学问题。本次研讨会将为可能的CMIP6制定初步规划。当前的时机提供了一个独特的机会来评估CMIP5进程的成就和突出问题，并利用它来帮助告知可以考虑纳入CMIP6进程的实验设计和研究方向的发展。有趣和有用的科学问题包括以下内容：(i)土地利用-气溶胶- esm应用-与几个共享社会经济途径（ssp）相互作用，这些途径显示出与rcp截然不同的结果；可逆性或地球工程；（iii）更理想化的实验，例如1%的运行，但对于其他强迫，理想化的气溶胶、臭氧、土地利用，如1%的运行；十年预测和极值；系统性偏见；热带气旋以及风暴和环流变化的其他方面的高分辨率时间片试验；热带气旋、极端事件和环流变化的高分辨率耦合模拟；（八）与陆地冰相结合，以便更好地估计全球和区域海平面上升。该研讨会将直接使USGCRP的各机构受益，并有助于促进气候预测和可预测性以及为未来的国际评估做准备的科学进程。

These funds support a Workshop entitled 'Next generation climate change experiments needed to advance knowledge and for assessment of CMIP6' organized by the Aspen Global Change Institute. As we approach the end of the Intergovernmental Panel for Climate Change fifth assessment report (IPCC AR5) process and the culmination of the extensive model intercomparison exercise of Coupled Model Intercomparison Project (CMIP5), emerging gaps in scientific understanding lead to opportunities for new climate model experiments that explore aspects of the science best addressed through a coordinated set of model experiments. This workshop will set the initial planning for a possible CMIP6. The current timing affords a unique opportunity to assess the accomplishments and outstanding issues with the CMIP5 process and use this to help inform the development of experimental design and research directions that can be considered for inclusion in the CMIP6 process. The range of interesting and useful science questions include the following: (i) Land use -aerosols-ESM applications-interact with a couple of the Shared Socio-economic Pathways (SSPs) that show quite different outcomes from RCPs; (ii) Reversibility or geo-engineering; (iii) More idealized experiments, e.g. 1% runs but for other forcings, idealized aerosol, ozone, land use, like the 1% runs; (iv) Decadal prediction and extremes; (v) Systematic biases; (vi) Very high resolution time slice experiments for tropical cyclones and other aspects of storms and circulation changes; (vii) Higher resolution coupled simulations for tropical cyclones, extremes, and circulation changes; and (viii) Coupled land ice for better estimates of global and regional sea level rise.The workshop will directly benefit agencies of the USGCRP and their contribution to the advancement of climate projections and predictability and the scientific process leading up to the future international assessments.
