A Collaborative Effort Toward Adding an Interactive Dynamical Vegetation Component to the NCAR Community Climate System Model (CCSM) Land Model

该项目将在地球系统的数值模型中进一步开发和测试改进的植被过程表示法，包括植被变化的动力学。首席研究人员将继续与国家大气研究中心(NCAR)的科学家合作，推动交互式植被部分的工作，使其成为社区气候系统模式(CCSM)的组成部分。计划进行一系列模拟，从离线陆地-植被模拟开始，耦合气候模型-固定植被模拟，多世纪前工业化耦合模拟，漫长的中全新世模拟，以及短暂的全球变暖整合。本项目中提出的问题在这些纯粹的建模工作之外也有应用。这项工作的最终成果将是CCSM内陆地过程的复杂表示，并可供其他用户免费使用，对我们理解当前和未来的气候模式和变化具有重要意义。更好地了解当前的人为影响对社会的好处是深远的。

The project will further develop and test improved representations of vegetation processes, including the dynamics of vegetation change, within numerical models of the earth system. The principal investigator will continue to collaborate with scientists at the National Center for Atmospheric Research (NCAR) to advance work on the interactive vegetation component as it progresses towards becoming an integral part of the Community Climate System Model (CCSM). A series of simulations are planned starting with offline land-vegetation simulations, coupled climate model-fixed vegetation simulations, multi-century pre-industrial coupled simulation, a long mid-Holocene simulation, and a transient global warming integration. The issues raised in this project have application outside these purely modeling efforts. The final product of this work will be a sophisticated representation of terrestrial processes within the CCSM, and freely available to other users, with important implications for our understanding of current and future climate patterns and changes. Societal benefits from improved understanding of current anthropogenic impacts are far-reaching.
