Physical Oceanography Distributed Active Archive Center (PO.DAAC)

The Physical Oceanography Distributed Active Archive Center (PO.DAAC) is the NASA data center responsible for archiving and distributing data relevant to the physical state of the ocean. Most of the data products available at PO.DAAC were obtained from Earth observing satellites and are primarily intended for use in scientific research. You can view data on global ocean topography and gravity, sea surface temperature, ocean winds, ocean circulation and ocean currents via the links below.

物理海洋学分布式主动档案中心（PO.DAAC）是美国国家航空航天局（NASA）下属的数据中心，负责存档和分发与海洋物理状态相关的数据。PO.DAAC提供的大多数数据产品来源于地球观测卫星，主要用于科学研究。您可通过以下链接查看全球海洋地形与重力、海表温度、海洋风场、海洋环流及洋流相关数据。
