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 the improved algorithms that evolve through time. A new version of OSCAR (ocean currents), which is CF compliant, is now available and based on the new AVISO Sea Level Anomaly (SLA) grids. There is a near real time SLA dataset from SARAL/AltiKa with orbit corrections based from crossovers OSTM/Jason-2 GPS orbit. The latest and greatest reprocessing of Jason-1 into version E will be completed by the end of this year.

PO.DAAC continues to provide users with improved abilities to access and visualize its data and metadata holdings by updating its current tools. The 2-D State Of The Ocean (SOTO) visualization tool now has a flat map that wraps, so there is a continuous spatial display of data when panning. There are also PO.DAAC's web services, that allow users to grab meta/data with just a couple of lines of code. PO.DAAC is also improving the way we convey information for our data management and usage metrics. A best practices webpage has been developed so users and other data managers can see how PO.DAAC manages its data and the data lifecycle. Digital Object Identifiers (DOI) are going to be registered for all of PO.DAAC's distributed datasets to provide users with easier ways to cite data and to collect usage metrics.
