The GLOBE Program: Greenhouse Gases, Ozone Depletors, and the Changing Composition of the Earth's Atmosphere

哈利勒：为响应全球学习和观测造福环境项目（GLOBE）的机会公告，本项目旨在实现GLOBE的目标和宗旨，即通过全球信息网络将科学家和学生联系起来，最终目标是更好地了解地球环境及其内部发生的变化。该项目的具体目标是实现全球环境规划署关于大气和气候的目标的一个重要部分。该项目将完成三项任务：1)通过提供实践经验、真实数据和基于计算机的学习工具，向K-12学生讲授大气成分、全球变化和气候。2)在大陆站点获取与气候变化和臭氧消耗有关的关键微量气体的新数据，这些站点需要进行此类测量，但尚未进行此类测量。直接通量测量补充了大气测量，以研究源和汇。3)建立一种廉价而高效的方法，使该项目结束后，在GLOBE的下一阶段，大气成分可以成为核心测量。

Khalil In response to an Announcement of Opportunity for the Global Learning and Observations to Benefit the Environment Program (GLOBE) this project is designed to meet the GLOBE goals and objectives of linking scientists and schoolchildren in a global information network with the ultimate goal of better understanding the Earth's environment and changes that take place within it. The specific goals of this project are to fulfill an important part of GLOBE's objectives dealing with the atmosphere and climate. Three tasks are to be accomplished: 1) To teach K-12 students about atmospheric composition, global change and climate by providing hands on experience, real data and computer based learning tools. 2) To obtain new data on key trace gases involved in climate change and ozone depletion, at continental sites, where such measurements are needed and have not been taken. The atmospheric measurements are supplemented by direct flux measurements to study sources and sinks. And 3) to establish a methodology that is inexpensive and ef ficient so that in the next phase of GLOBE, after this project ends, atmospheric composition can become a core measurement.
