Physical Oceanography Distributed Active Archive Center

The Physical Oceanography Distributed Active Archive Center (PO.DAAC) is an element of the Earth Observing System Data and Information System (EOSDIS). The EOSDIS provides science data to a wide community of users for NASA's Science Mission Directorate. Since the launch of NASA's first ocean-observing satellite, Seasat, in 1978, PO.DAAC has become the premier data center for measurements focused on ocean surface topography (OST), sea surface temperature (SST), ocean winds, sea surface salinity (SSS), gravity, ocean circulation and sea ice.In addition to providing access to its data holdings, PO.DAAC acts as a gateway to data stored at other ocean and climate archives. This and other tools and services enable PO.DAAC to support a wide user community working in areas such as ocean and climate research, applied science and industry, natural resource management, policy making, and general public consumption.

物理海洋学分布式主动存档中心（PO.DAAC）是地球观测系统数据与信息系统（EOSDIS）的组成部分。EOSDIS为美国宇航局科学任务部的广大用户群体提供科学数据。自1978年美国宇航局首颗海洋观测卫星Seasat发射以来，PO.DAAC已成为专注于海洋表面地形（OST）、海面温度（SST）、海洋风、海面盐度（SSS）、重力、海洋环流和海冰测量的顶级数据中心。除了提供对其数据存储的访问外，PO.DAAC还充当其他海洋和气候存档中存储数据的门户。这些以及其他工具与服务使得PO.DAAC能够支持在海洋与气候研究、应用科学和工业、自然资源管理、政策制定以及公众消费等领域工作的广泛用户群体。
