The Importance of Soil Moisture to Global Climate Change

Alfredo Huete回应全球学习和观察造福环境计划(GLOBE)的宣布该项目旨在实现全球的目标和目标，即将科学家和学童连接到一个全球信息网络中，最终目的是更好地了解地球环境和在地球上发生的变化。全球第二阶段的这项提议的主要目的是开发数据收集、数据分析、相关课程以及与美国和国外在土壤水分测量领域的大学前教育项目的计算机接口。将利用通过这项工作收集的数据，处理与直接土壤水分测量的汇总、表示和使用有关的几个重要科学问题，目的是改善和验证卫星和模型得出的土壤湿度。土壤水分值得特别关注，因为：它代表了陆地/大气界面的时空变化状态，是动植物生产力的关键因素，而且迫切需要一个广泛分布的地面测量网络，只有这种方案才能满足这一需求。

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.
