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

哈利勒在回应全球学习和观察造福环境方案(GLOBE)机会的公告时，该项目旨在实现全球的目标和目的，即在全球信息网络中将科学家和学童联系起来，最终目的是更好地了解地球环境和在地球上发生的变化。该项目的具体目标是实现全球大气和气候目标的重要组成部分。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学生传授大气成分、全球变化和气候方面的知识。2)在需要测量但尚未进行测量的大陆站点，获得与气候变化和臭氧消耗有关的关键痕量气体的新数据。大气测量得到直接通量测量的补充，以研究源和汇。3)建立一种廉价有效的方法，以便在全球下一阶段，在这个项目结束后，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.
