Modeling Canopy Carbon and Energy Balances in the Pan- Arctic: Scaling from Leaf to Region

RASTETTER海洋生物实验室该项目的目标是量化和提高对北极陆地生态系统碳储量变化的理解。冠层和土壤碳循环过程之间的平衡，以及它们与土壤湿度之间的相互作用，将有助于确定北极是发展成为一个重要的碳汇还是碳源。该项目将特别关注树冠碳和水交换的建模，并综合现有项目中实验组成部分收集的信息。将采用一系列模型，从经过验证的基于过程的模型中衍生出稳健的冠层碳和能量交换区域模型。该项目将整合从Toolik Lake LTER站点收集的信息，建立联系，以促进构建更简单和粗略比例的冠层过程模型，第三，创建适当比例的冠层过程表示，供其他区域建模工作使用。

ABSTRACT OPP-9614038 RASTETTER MARINE BIOLOGICAL LABORATORY The goal of this project is to quantify and to improve understanding of changes in carbon storage in terrestrial Arctic ecosystems. The balance between canopy and soil carbon cycling processes, and the interactions between them and soil moisture, will help determine whether the Arctic develops as an important sink or source for carbon. This project will focus specifically on modelling canopy carbon and water exchange, and synthesize information gathered in experimental components of existing programs. A hierarchy of models will be employed that will produce robust regional models of canopy carbon and energy exchange, derived from validated process-based models. The project will integrate information collected from Toolik Lake LTER site, make linkages that will facilitate the construction of simpler and coarsely-scaled models of canopy proecess, and third, create suitably scaled representations of canopy process for use by other regional modelling efforts.
