The Importance of Soil Moisture to Global Climate Change

Huete，Alfredo 全球学习和观察有益于环境计划（地球仪）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，最终目的是为了更好地了解地球环境及其变化。地球仪第二阶段的主要目的是开发数据收集，数据分析，相关课程和计算机接口与美国和国外的土壤湿度测量领域的大学预科教育计划。将利用通过这一努力收集的数据，处理与直接土壤湿度测量的汇总、代表性和效用有关的几个重要科学问题，以便改进和验证卫星得出的和模型得出的土壤湿度。土壤湿度值得特别关注，因为：它代表了土地/大气界面的时间和空间变化状态，它是植物和动物生产力的一个关键因素，因为对广泛分布的地面测量网络的压倒性需求，只有这种建议才能满足。

Huete, Alfredo 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. This proposal to GLOBE PHASE II has as its primary intent to develop data collection, data analysis, related curricula and a computer interface with pre-college educational programs within the U.S. and abroad in the area of soil moisture measurements. Several important scientific issues regarding the aggregation, representation and utility of direct soil moisture measurements for the purpose of improving and validating satellite-derived and model-derived soil moisture will be addressed with the data collected through this effort. Soil moisture deserves special focus, because: it represents the temporal and spatial variable state of the land/atmosphere interface, it is a critical factor in plant and animal productivity and because there is an overwhelming need for a widely distributed ground measurement network that only this kind of proposal can satisfy.
