This grant provides partial support for a workshop on the behavior of the coupled land - atmosphere system over the 20th century, in the context of the international Coupled Carbon Cycle Climate Model Intercomparison Project (C4MIP). Phase 1 of C4MIP is now underway, and the workshop, to take place in September 2003, is to compare research results through analyzes of the simulations conducted to-date. The workshop will analyze the simulations performed for phase 1, with the following 3 goals:1. Compare the sensitivities of the coupled atmosphere-terrestrial biosphere models to historical forcing and determine how much of the range in overall sensitivity of the 'future' response can be seen in the historical period.2. Decompose model sensitivity into (a) climatic responses to CO2 and SST forcing and (b) terrestrial carbon cycle responses to climate and CO2 changes3. Compare elements of the simulated carbon flux and atmospheric concentration fields with available historical reconstructions.Based on the results of Phase 1, a second phase will be outlined at the workshop, in order to build on what has been learned to date. Broader impactsHuman influences on the Earth's carbon cycle, primarily through fossil fuel burning and land use changes, is affecting the world climate. This project strives to help develop the understanding and predictive modeling capabilities that will help provide sound scientific information on this issue to those who make environmental/energy policy. This is a potentially large benefit to human societies.

这笔赠款为在国际耦合碳循环气候模型比对项目（C4MIP）背景下举办的关于 20 世纪耦合陆地-大气系统行为的研讨会提供了部分支持。 C4MIP 的第一阶段正在进行中，研讨会将于 2003 年 9 月举行，旨在通过分析迄今为止进行的模拟来比较研究结果。研讨会将分析第一阶段进行的模拟，并实现以下 3 个目标：1．将大气-陆地生物圈耦合模型的灵敏度与历史强迫进行比较，并确定“未来”响应的总体灵敏度范围在历史时期可以看到多少。2．将模型敏感性分解为（a）气候对二氧化碳和海温强迫的响应以及（b）陆地碳循环对气候和二氧化碳变化的响应3。将模拟碳通量和大气浓度场的元素与可用的历史重建进行比较。根据第一阶段的结果，研讨会将概述第二阶段，以便以迄今为止所学到的知识为基础。更广泛的影响人类对地球碳循环的影响，主要是通过化石燃料燃烧和土地利用变化，正在影响世界气候。 该项目致力于帮助发展理解和预测建模能力，这将有助于向环境/能源政策制定者提供有关该问题的可靠科学信息。 这对人类社会来说是一个潜在的巨大利益。
