Physical Oceanography Distributed Active Archive Center (PO.DAAC)

• Physical Oceanography Distributed Active Archive Center
  • The Physical Oceanography Distributed Active Archive Center (PO.DAAC) is a NASA Earth Observing System Data and Information System (EOSDIS) data center managed by the Earth Science Data and Information System (ESDIS) Project. The PO.DAAC is operated by Jet Propulsion Laboratory (JPL) in Pasadena, California. 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.
