Climates of deep time, i.e. tens to hundreds of millions of years ago provide a unique opportunity to understand Earth's climate processes in an integrated fashion. The climates of these time periods include warm hothouse and cold icehouse climate regimes. Climate models are currently being applied to study how these climates are maintained and how the climate system changes through geologic time. A unique challenge for integrating the climate deep time simulations is that many geoscientists, interested in these simulations, are not climate modelers. This grant supports a deep time liaison position at the National Center for Atmospheric Research to aid the deep time community in simulating climates of the deep past. The liaison will work with university faculty who need support to carry out pre-quaternary climate simulations with the Community Climate System Model (CCSM). The specific tasks of the liaison will include: collaborations with university investigators to develop tools and documentation to facilitate the setting up of deep time CCSM climate simulations, the carrying out of deep time CCSM simulations on NCAR supercomputers, the facilitation of archiving model output and supporting a web based system to make output available to the university community, the transfer of deep time model simulation output to the university community, the diagnosis of CCSM deep time climate simulations using diagnostic tools, and the sponsoring of training workshop to the community at large on deep time climate modeling. The availability of the liaison services for the user community will be made known through the CCSM Paleoclimate Working Group, national meetings, and workshops focused on specific deep time events.

深时间的气候，即数千万至数亿年前的气候，为以综合方式了解地球的气候过程提供了独特的机会。这些时间段的气候包括温暖的温室和寒冷的冰室气候制度。气候模型目前正被应用于研究这些气候是如何维持的，以及气候系统如何在地质时期发生变化。整合气候深时模拟的一个独特挑战是，许多对这些模拟感兴趣的地球科学家并不是气候建模者。这项拨款支持国家大气研究中心的深时联络职位，以帮助深时社区模拟过去的气候。联络员将与需要支持的大学教师合作，利用社区气候系统模型（CCSM）进行前第四纪气候模拟。联络员的具体任务包括：与大学研究人员合作，开发工具和文件，以促进建立深时CCSM气候模拟，在NCAR超级计算机上进行深时CCSM模拟，促进存档模型输出，并支持基于网络的系统，使输出可供大学社区使用，将深时模式模拟输出转移到大学社区，使用诊断工具对CCSM深时气候模拟进行诊断，并为整个社区举办深时气候模拟培训讲习班。将通过CCSM古气候工作组、国家会议和侧重于特定深时事件的讲习班，向用户社区提供联络服务。
