Goddard Earth Sciences Data and Information Services Center

One of twelve NASA Science Mission Directorate (SMD) Data Centers that provide Earth science data, information, and services to research scientists, applications scientists, applications users, and students. The GES DISC is the home (archive) of NASA Precipitation and Hydrology, as well as Atmospheric Composition and Dynamics remote sensing data and information. The DISC also houses the Modern Era Retrospective-Analysis for Research and Applications (MERRA) data assimilation datasets (generated by GSFC’s Global Modeling and Assimilation Office), and the North American Land Data Assimilation System (NLDAS) and Global Land Data Assimilation System (GLDAS) data products (both generated by GSFC's Hydrological Sciences Branch).

作为美国国家航空航天局（NASA）科学任务部（SMD）设立的十二个数据中心之一，本数据中心致力于为研究科学家、应用科学家、应用用户及学生提供地球科学数据、信息与服务。地球系统数据和信息中心（GES DISC）是NASA降水和水利、大气成分与动力学遥感数据及信息的存储库（档案）。该中心亦容纳了现代时代研究与应用回顾分析（MERRA）数据同化数据集（由NASA全球建模与同化办公室生成），以及北美陆地数据同化系统（NLDAS）和全球陆地数据同化系统（GLDAS）数据产品（均由NASA水文科学分支生成）。
