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存档中心（Physical Oceanography Distributed Active Archive Center，缩写PO.DAAC）是美国国家航空航天局（NASA）旗下负责归档与分发海洋物理状态相关数据的专业数据中心。该中心提供的绝大多数数据产品均源自地球观测卫星，主要用于科学研究。您可通过下方链接查看全球海洋地形与重力场、海表温度、海洋风场、大洋环流以及海流等相关数据。
