The Physical Oceanography Distributed Active Archive Center (PO.DAAC) at the Jet Propulsion Laboratory is the NASA data center responsible for archiving and distributing data relevant to the physical state of the ocean. With the rapid increase in data volume and the expansion of our science user community, the ability to reliably capture science artifacts and promptly make the data products available to our users is driving the next generation of the PO.DAAC data management system. Modern data management systems must be adaptable to diverse science data formats, scalable to meet the mission’s quality of service requirements, and able to manage the life-cycle of a given science product. This talk makes three contributions to the area of modern data archive systems. First, it describes the data archive pipeline developed for PO.DAAC. The Data Management and Archive System (DMAS) is a distributed, transaction-oriented data archive system. Second, it describes the DMAS architecture in the area of metadata capturing, state-driven product life-cycle management, load balancing, and significant event capturing and reporting. Finally, it presents the application of the DMAS for the Group for High-Resolution Sea Surface Temperature (GHRSST) and Advanced SCATterometer (ASCAT) projects.
