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.

摘要OPP-9614038 Rastetter海洋生物实验室该项目的目的是量化和提高对陆地北极生态系统碳储存变化的理解。 冠层和土壤碳循环过程之间的平衡以及它们与土壤水分之间的相互作用，将有助于确定北极是否发展为碳的重要水槽或来源。 该项目将专门用于建模冠层碳和水交换，并合成在现有程序的实验组件中收集的信息。 将采用模型的层次结构，该模型将产生稳健的区域模型的顶篷碳和能量交换，这些模型来自经过验证的基于过程的模型。 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，更粗糙的冠层专业模型，第三，创建适当扩展的划定范围代表，以供其他区域建模工作使用。
