The principal goal of this CAREER project is to understand and quantify the impacts of contemporary deforestation and projected future deforestation on climate, hydrology, and terrestrial ecosystems. A multi-scale analysis will be conducted with the following objectives (i) to determine how the size, shape, and organization of deforested areas alter atmospheric dynamics; and (ii) to study how the atmosphere communicates these changes to intact areas of rainforest, other parts of South America and other parts of the world. Climate vegetation feedbacks will also be analyzed. One of the deliverables of this project is an integrated framework for understanding how Amazon deforestation affects local, regional, and global climate, hydrology, and ecosystems. This framework will be extended to analyze deforestation in tropical Asia and Africa.The research focuses on integrating research and education at the Middle School level. The primary goal is to bring improved understanding of Earth's atmosphere, land surface, and human elements of global change into the middle school classroom. A new teacher-in-service unit will be developed and organized under the aegis of QUEST, a professional development program with a 25-year track record of success and administered by Princeton University's Program in Teacher Preparation. Students will gain hands-on experience collecting and analyzing local weather station data, and will also be taught how to access Amazon-relevant data from the Internet. Students will present their work at a local science fair. This research will also support a graduate student. Thus this project has substantial broader impacts.

该职业项目的主要目标是了解和量化当代森林砍伐和预计未来森林砍伐对气候、水文和陆地生态系统的影响。将进行多尺度分析，目标如下：(i) 确定砍伐森林地区的大小、形状和组织如何改变大气动态； (ii) 研究大气如何将这些变化传达给完整的雨林地区、南美洲其他地区和世界其他地区。气候植被反馈也将被分析。该项目的成果之一是建立一个综合框架，用于了解亚马逊森林砍伐如何影响当地、区域和全球气候、水文和生态系统。该框架将扩展到分析热带亚洲和非洲的森林砍伐。该研究的重点是整合中学一级的研究和教育。主要目标是让中学课堂更好地了解地球大气、陆地表面和全球变化的人类因素。将在 QUEST 的支持下开发和组织一个新的在职教师单位，该专业发展计划拥有 25 年的成功记录，由普林斯顿大学教师准备计划管理。学生将获得收集和分析当地气象站数据的实践经验，还将学习如何从互联网访问亚马逊相关数据。学生将在当地的科学博览会上展示他们的作品。这项研究还将支持一名研究生。因此，该项目具有更广泛的影响。
