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 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 consists of various segments addressing GLOBE Program needs: support for existing protocols, development of new protocols, and scientific research with GLOBE data. This proposal will support the current set of GLOBE soil measurement protocols, with the cooperation of the USDA, Cornell University, ISRIC (The Netherlands). The project will use GLOBE student-collected data to derive and validate algorithms for physical and chemical soil/plant/atmospheric process simulation models, including the General Purpose Simulation Model of the Earth Atmosphere System (GAPS). The GLOBE soil data will be used to determine baseline estimates of soil quality within various ecosystems and land use scenarios. Seasonal measurements of surface soil characteristics will assess regional changes in soil quality. This proposal will also support the development of materials for education that will include soil science in the context of Earth Systems Science. Scientists, students, and the general public will be able to better understand the role of living soil in ecosystems and their role in the care of our natural resources.

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，即将全球信息网络中的科学家和学童与更好地了解地球环境及其内部发生的变化这一最终目标联系起来。该提案由解决GLOBE计划需求的各个部分组成：支持现有协议，开发新协议以及使用GLOBE数据进行科学研究。在美国农业部、康奈尔大学、ISRIC（荷兰）的合作下，该提案将支持目前的GLOBE土壤测量方案。该项目将使用GLOBE学生收集的数据来推导和验证物理和化学土壤/植物/大气过程模拟模型的算法，包括地球大气系统通用模拟模型（GAPS）。全球土壤数据将用于确定各种生态系统和土地利用情景下土壤质量的基线估计。表层土壤特征的季节性测量将评估土壤质量的区域变化。该提案还将支持开发教育材料，其中将包括地球系统科学背景下的土壤科学。科学家、学生和公众将能够更好地了解生态系统中活土壤的作用，以及它们在保护自然资源方面的作用。
