Methods and Models for Evaluating Vegetation Feedbacks on the Climate System

小行星9711484 PI将开发新的方法和模型，以评估植被对气候系统的反馈潜力。 特别是，他们计划将IBIS和综合动力生物圈模型与NCAR气候系统模型（CSM）耦合。 使用动态耦合CSM/IBIS气候-植被模式，他们将探索植被反馈机制及其在未来气候情景中的潜在作用。 这些新的耦合模式的开发和评估将为全球环境变化的综合分析提供一个更全面的框架。 最重要的是，这项工作将有助于阐明植被反馈对气候系统的潜在作用，以及瞬时气候变化对陆地生物圈的影响。 试图对全球变化进行综合评估时，必须考虑到生物圈对气候系统作出重大反馈的可能性。 该研究由NSF综合评估倡议的方法和模型资助。

9711484 Foley The PI's will develop new methods and models to evaluate the potential for vegetation feedbacks on the climate system. In particular, they plan to couple IBIS, and integrated dynamical biosphere model, to the NCAR Climate system Model (CSM). Using the dynamically coupled CSM/IBIS climate-vegetation model, they will then explore vegetation feedback mechanisms and their potential role in future climate scenarios. The development and evaluation of these new coupled models will provide a more holistic frame work for preforming integrated analyses of global environmental change. Most importantly this work will help elucidate the potential role of vegetation feedbacks on the climate system, and the impact of transient climate change on the terrestrial biosphere. Attempts at an integrated assessment of global change must consider the possibility of substantial biospheric feedbacks on the climate system. This research is funded under the NSF methods and Models for Integrated Assessment initiatives.
