A consortium led by George Mason University has been funded by NASA's Working Prototype Earth Science Information Partner (WP-ESIP) program to develop, implement, and operate a distributed data and information system. The system will address the research needs of seasonal to interannual scientists whose research focus includes phenomena such as El Nino, monsoons and associated climate studies. The system implementation involves several institutions using a multitiered client-server architecture. Specifically the consortium involves an information system of three physical sites, GMU, the Center for Ocean-Land-Atmosphere Studies (COLA) and the Goddard Distributed Active Archive Center, distributing tasks in the areas of user services, access to data, archiving, and other aspects enabled by a low-cost, scalable information technology implementation. The project can serve as a model for a larger WP-ESIP Federation to assist in the overall data information system associated with future large Earth Observing System data sets and their distribution. The consortium has developed innovative information technology techniques such as content based browsing, data mining and associated component working prototypes; analysis tools particularly GrADS developed by COLA, the preferred analysis tool of the working seasonal to interannual communities; and a Java front-end query engine working prototype.","PeriodicalId":120937,"journal":{"name":"Proceedings.

The associated measurement data need to be stored and studied to understand the Earth system processes. The ability of interactive content-based browsing, i.e., browsing or searching the content to narrow-down the interesting portions of data sets prior to actually accessing or ordering full data sets, is highly desirable for any Earth science data information system. However the large volumes of archived and future Earth science remote sensing data are clearly a serious challenge for an interactive browsing process. In this paper a pyramid data model is introduced to support interactive content-based browsing and knowledge discovery for a wide variety of Earth science remote sensing data sets. By using multi-level precomputation and robust nonparametric approximation procedures, the interactive browsing performance can be enhanced greatly. An initial implementation and testing of this data model has been carried out through our research prototype system, Virtual Domain Application Data Center (VDADC). Future implementations are planned for our Seasonal to Interannual Earth Science Information Partner (SIESIP) project.","PeriodicalId":120937,"journal":{"name":"Proceedings.
