Oak Ridge National Laboratory Distributed Active Archive Center for Biogeochemical Dynamics

The Oak Ridge National Laboratory Distributed Active Archive Center (ORNL DAAC) for biogeochemical dynamics is one of the National Aeronautics and Space Administration (NASA) Earth Observing System Data and Information System (EOSDIS) data centers managed by the Earth Science Data and Information System (ESDIS) Project. The ORNL DAAC archives data produced by NASA's Terrestrial Ecology Program. The DAAC provides data and information relevant to biogeochemical dynamics, ecological data, and environmental processes, critical for understanding the dynamics relating to the biological, geological, and chemical components of Earth's environment.

美国橡树岭国家实验室的生物地球化学动力学分布式主动存档中心（ORNL DAAC）是隶属于美国国家航空航天局（NASA）地球观测系统数据与信息系统（EOSDIS）的地球科学数据与信息系统（ESDIS）项目管理的数据中心之一。ORNL DAAC存档了由NASA陆地生态学计划产生的数据。该中心提供与生物地球化学动力学、生态数据和环境过程相关的数据和信息，这些数据和信息对于理解地球环境中生物、地质和化学成分之间的相互作用至关重要。
