摘　　要：通过引入OPeNDAP(网络数据访问协议开源项目)协议,设计了基于OPeNDAP的地球科学数据共享概念框架,提出了面向地球系统数据记录的数据共享系统体系结构及其工作流程。选取全球1948-2006年间的不同空间尺度和时间尺度的降水、地面气压、比湿、空气温度和风速等信息数据作为共享数据源,将上述体系结构应用在MEaSUREs(让地球系统数据记录在研究环境中应用)研究项目中,开发了地球信息科学数据分发共享原型系统及应用实例,实现了面向所有数据使用者的协议透明共享,并可通过二维、三维以及基于时间维的四维动态模拟,为辅助政府相关部门决策支持提供依据。Based on OPeNDAP, Opensource Project for a Network Data Access Protocol, a conceptual framework is designed for Earth Science Data Sharing and an Earth System Data Record （ESDR） oriented data sharing architecture is proposed together with its workflow. Based on the above system architecture, the ESDRs data distribution prototype is developed to distribute the data sets freely to the earth science community. Using the global data of precipitation, surface pressure, specific humidity, air temperature and wind speed during the period of 1948-2006 with different spatial and temporal scales as the shared data resources, the proposed architecture is applied to the project MEaSUREs, Making Earth System data records for Use in Research Environments. An Earth Information Science Data Sharing prototype is developed with application instances, in which transparent sharing is realized based on the protocol oriented for all data users. Also, 2D, 3D and timedimension based 4D dynamic emulations are supported to provide the government with reference for their decision making.
