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. New datasets include ALES, Integrated Multi-Mission Ocean Altimeter Data for Climate Research Version 3 and a gridded Sea Surface Height Anomaly dataset.

To assist in serving out the numerous datasets at PO.DAAC, various tools and services are available with improvements from last year. The swath subsetting tool, HiTIDE, is updated and has an entire new look and feel. If users want assistance in downloading and accessing PO.DAAC data there are now data recipes that can be found in the forum. PO.DAAC Drive is available to provide a smoother transition accessing PO.DAAC data when registration for data access becomes mandatory.
