This project will build a comprehensive model to simulate interactions between energy, water, and carbon dioxide using data collected from tundra regions in northern Alaska. The model will be used to examine the role of global climate change on terrestrial ecosystems in an area that is predicted to be the first to feel the greatest effects of global warming. The project will utilize satellite images and data, data collected from recent field programs, and output from other models of the individual environmental components. The project will develop a regional simulation of climate impacts on terrestrial ecosystems and address the questions of energy and water balance in the Arctic system. The research will identify critical gaps in the understanding of climate-sensitive variables in the Arctic terrestrial ecosystem as well as the exchange of carbon dioxide with the atmosphere. Therefore, the project will be an important contribution to understanding the biocomplexity of the environment in an area undergoing rapid climate change at present.

该项目将利用从阿拉斯加北方苔原地区收集的数据建立一个综合模型，模拟能源、水和二氧化碳之间的相互作用。 该模型将用于研究全球气候变化对陆地生态系统的作用，该地区预计将首先感受到全球变暖的最大影响。 该项目将利用卫星图像和数据、从最近的实地方案中收集的数据以及个别环境组成部分的其他模型的产出。 该项目将对气候对陆地生态系统的影响进行区域模拟，并解决北极系统的能源和水平衡问题。 该研究将确定在北极陆地生态系统中对气候敏感的变量以及二氧化碳与大气的交换方面的关键差距。 因此，该项目将对了解目前正在经历快速气候变化的地区环境的生物复杂性作出重要贡献。
