What is the PO.DAAC Mission?


The mission of the PO.DAAC is to preserve NASA’s ocean and climate data and make these universally accessible and meaningful.

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 sea surface topography, ocean temperature, ocean winds, salinity, gravity, and ocean circulation.

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.

PO.DAAC User Working Group


The PO.DAAC User Working Group (UWG) is an external advisory group established by EOSDIS, made up of physical oceanographers, hydrologists, and data scientists, and tasked to:

  • Prioritize and provide guidance on PO.DAAC activities, science goals, including data acquisition, mechanisms to enhance user access to data, generation of value-added products, user support, operational functions, and development activities;
  • Provide strategic guidance and advice to NASA and PO.DAAC on annual work plan, long-term plans, objectives, priorities, target user communities, implementation approaches, and other issues;
  • Represent the user community in the development and operation of PO.DAAC’s products and services; Review the progress and performance of the DAAC relative to PO.DAAC’s mission;
  • Be ambassadors for PO.DAAC.
