Understanding Environmental Variability and Change through Modeling Soil Processes.

为了响应全球学习和观察惠及环境方案(GLOBE)机会的宣布，该项目旨在实现GLOBE的目标和目标，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。该提案包括满足Globe计划需求的各个部分：支持现有协议、开发新协议以及利用Globe数据进行科学研究。该提案将与美国农业部、康奈尔大学、ISRIC(荷兰)合作，支持目前的一套全球土壤测量协议。该项目将使用全球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(GAP)。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的土壤质量基线估计值。表层土壤特性的季节性测量将评估土壤质量的区域变化。这项提案还将支持开发教育材料，将土壤科学纳入地球系统科学的范畴。科学家、学生和普通公众将能够更好地了解活土壤在生态系统中的作用，以及它们在保护我们的自然资源方面的作用。

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.
