ORNL DAAC… What’s That? Oak Ridge National Laboratory’s (ORNL) Distributed Active Archive Center (DAAC) Located in Oak Ridge, Tennessee (near Knoxville) 1 of 7 DAACs created in the U.S. to provide data management for NASA’s Earth Observing System (EOS) ORNL DAAC’s Focus: Biogeochemical Cycles Provides strong support of the EOS Validation Program and major field campaigns (e.g., SAFARI, LBA)

ORNL DAAC Support of SAFARI Support Mercury Metadata EditorMercury Metadata Editor Software to allow easy metadata submission Internet online and “standalone” MELite Host Mercury to allow SAFARI participants to search and access data Harvests metadata from RDC and ORNL to create comprehensive SAFARI data catalog Single best starting point to find any/all SAFARI data Ground, aircraft, satellite, climatological, historical Provides information and pointer (URL, name/ ) for each data set

Data and documentation are downloaded directly from data provider User links to data provider’s server Mercury collects the metadata file and adds to SAFARI Catalog Participants query the Catalog and retrieve full metadata, including WWW links to data provider SAFARI Metadata Catalog ORNL Data and documentation Data provider uses Metadata Editor to create file containing general information and links to the data and documentation Participant Mercury Overview Data Provider
