Solid Earth Science ESDR System—2006
Principal Investigator (PI): Frank Webb, NASA's Jet Propulsion Laboratory
Building on NASA's investment in the measurement of crustal deformation from continuous GPS (CGPS) networks, we will build and deploy a Science Data System (SDS), which will provide mature, long-term Earth Science Data Records (ESDRs) that support NASA's Earth Surface and Interiors focus area and provide NASA's component to the EarthScope Plate Boundary Observatory.
This knowledge can be used for societal benefits from mitigation of natural hazards to K-12 science education. It will integrate the generation of ESI ESDRs with data analysis and exploration, product generation and modeling tools based on daily CGPS data from networks in western North America and a component of NASA's Global GPS Network (GGN) for terrestrial reference frame definition.
The system is expandable to multiple regional and global networks. The SDS will build upon mature data production, exploration, and analysis algorithms developed under NASA's Research, Education and Applications Solutions Network (REASoN), Advancing Collaborative Connections for Earth System Science (ACCESS), and Solid Earth and Natural Hazards (SENH) programs. The SDS will further ESI's goals in the Global GNSS Observation System (GGOS) by providing access to L0-L3 GPS data products, including raw receiver data with validated metadata, and long-term position, velocity, and strain time series for regional and global tracking networks.
The proposed project leverages the IT and Web Services developments of Southern California Integrated GPS Networks-REASoN and ACCESS projects. These projects have streamlined the access to data products for researchers and modelers, and leveraged the real-time components of the SENH applications project to create an on-the-fly interactive research environment through our modern data GPS Explorer portal.
Our IT system has been designed using modern tools and principles in order to be extensible to any geographic location, scale, natural hazard, and combination of geophysical sensor and related data.
We have built upon open GIS standards, particularly those of the Open Geospatial Consortium, and have used the principles of web service-based service oriented architectures to provide scalability and extensibility for new services and capabilities.
The community will be engaged in the development of these records through an advisory committee organized in collaboration with UNAVCO and the team's existing involvement in community driven science strategic planning, organization, and support for the broader EarthScope efforts.
Additionally, the team will continue to provide value and support to ongoing NASA Earth data system evolution by participating in the DSWG for Technology Infusion. The SDS will be NASA's primary geodetic contribution to the EarthScope project.
