Ornl daac what s that
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
ORNL DAAC Support of SAFARI

  • Support Mercury 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/email) for each data set
