The Physical Oceanography Distributed Active Archive Center (PO.DAAC) is NASA’s data center responsible for data management and distribution of satellite oceanographic data, as well as providing support for its scientific user base. PO.DAAC’s data holdings relevant to Ocean Surface Topography include sea surface height and significant wave height from TOPEX/Poseidon, Jason-1, OSTM/Jason-2, SARAL/AltiKa and gravity measurements from GRACE. Our data holdings are constantly being updated to accommodate improved algorithms that evolve through time. Jason-1 will be reprocessed into version E and be available to the user community this year. Other updates are version 3 of the Integrated Multi-Mission Ocean Altimeter Data for Climate Research and US West Coast coastal altimetry. Coastal altimetry for Jason-2 from ALES is also available at PO.DAAC.

There will be a new user registration to access data at PO.DAAC, along with the rest of NASA’s DAACs. PO.DAAC plans on having a transition period early next year to give users a chance to get use to the new system before switching over. Other new services include datasets having Digital Object Identifiers (DOI) so that users can now reference datasets as a citation rather than in the acknowledgments. The forum has been updated to distribute a digest keep users who are signed up on the latest announcements and topics being discussed.
