This project will improve understanding of terrestrial carbon sinks by linking process-level biological information obtained for individual plants or ecosystems over short time scales with observations and models that characterize the large spatial domain and long time scales of regional and global concern. The P.I. will obtain comprehensive observations and use archived data integrated across several spatial and temporal scales, including tower and aircraft flux measurements and forest biomass inventories, to develop an integrated ecosystem-atmosphere model that captures both slow and fast ecosystem processes. The combined results will provide quantitative constraints to the carbon budget at regional scales. The integrated model will be optimized using atmospheric and biospheric data that quantitatively link properties of the terrestrial biosphere-atmosphere system with the underlying fundamental biological and physical processes. The project has an outreach program that includes an interactive CD-ROM with information on the carbon cycle and climate change and a module for having students conduct hypothesis testing using project data.

该项目将通过将短期内从单个植物或生态系统获得的过程级生物信息与表征区域和全球关注的大空间域和长期尺度的观测和模型联系起来，增进对陆地碳汇的理解。 P.I.将获得全面的观测结果，并使用跨多个空间和时间尺度整合的存档数据，包括塔架和飞机通量测量以及森林生物量清单，开发一个综合的生态系统-大气模型，捕捉缓慢和快速的生态系统过程。 综合结果将为区域尺度的碳预算提供定量约束。 该综合模型将利用大气和生物圈数据进行优化，这些数据将陆地生物圈-大气系统的特性与潜在的基本生物和物理过程定量联系起来。 该项目有一个外展计划，其中包括一张包含碳循环和气候变化信息的交互式光盘，以及一个让学生使用项目数据进行假设检验的模块。
