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

哈利勒在回应一项关于全球学习和观察有益于环境计划（GLOBE）的机会的公告时说这个项目的目的是为了实现全球信息网络中的科学家和学生之间的联系，最终目的是更好地了解地球环境及其变化。这个项目的具体目标是实现以下目标的重要组成部分：全球方案处理大气层和气候的目标。三个任务是要完成：1）教K-12学生有关大气成分，全球变化和气候，通过提供实践经验，真实的数据和计算机为基础的学习工具。2)在需要但尚未进行此类测量的大陆地点获取与气候变化和臭氧消耗有关的关键痕量气体的新数据。大气测量还辅以直接通量测量，以研究源和汇。3）建立一种廉价而有效的方法，以便在GLOBE的下一阶段，在该项目结束后，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.
