Advanced Applications: Earth Observing System: Measuring the Benefit of Internet2 for Science Data Distribution

Time 10/03/01 04:45PM-06:00PM

Session Abstract

The Earth Observing System (EOS) is the centerpiece of NASA's Earth Science Enterprise (ESE). It consists of a science component and a data system supporting a coordinated series of polar-orbiting and low inclination satellites for long-term global observations of the land surface, biosphere, solid Earth, atmosphere, and oceans. By enabling improved understanding of the Earth as an integrated system, the EOS program has benefits for us all." The data system mentioned in this quote from the EOS program office comprises a distributed collection of data archive sites and intermediate data reduction facilities and subsystems. Once the science data products have been developed they are made available to Principal Investigators at sites around the world, with a significant number located at Internet2 universities. The data products, usually exceeding 300 Megabytes, are routinely transported from NASA's archive sites, with some universities drawing more that 100 Gigabytes per day in FTP transfers. The Internet2 is facilitating the delivery these products at significantly reduced download times, increasing the efficiency of the analysis process. This talk will discuss the tools developed to track the quantity and efficiency of the delivery of these products, and will show examples of daily and longer-term reports.
