## 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 Editor ](file:///../../../../Program%20Files/Field%20Instruments/MELite/MELite.exe)_
- 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

## Mercury Overview

**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**
