Data available at the ORNL DAAC have been collected by various organizations for different purposes and research projects. To aid in organizing these products, we have assigned each product archived at the ORNL DAAC to one of four broad project categories:

• Field Campaigns
• Validation Data
• Regional and Global Data
• Model Archive

You may navigate to data or model products associated with these project areas by using the menu or by clicking on the specific project links included on this page. If you don't know the project for a particular product, you can use our search system to search for products by attribute (for example, variable measured, spatial extent, investigator).

Field campaigns are projects that typically involve numerous investigators collectively studying selected aspects of the ecology and biogeochemistry of a particular region or biome. These projects are usually short in duration and involve the collection of both in situ and remote-sensing and GIS data. More...

The goal of the EOS Validation Program is the comprehensive assessment of all EOS science data products. The ORNL DAAC supports these assessments by compiling data such as leaf area index (LAI) and net primary productivity (NPP) for global test sites to compare with satellite-derived products. Ground-based observations coincident with satellite data are unique and provide the data necessary to develop, calibrate, and validate ecosystem models. More...

The ORNL DAAC compiles, archives, and distributes regional and global data (RGD) that may be used to improve our understanding of the structure and function of ecosystems. The DAAC also provides a search and retrieval system -- Mercury -- for obtaining regional and global data held by other data centers and links to data centers that offer Regional and Global Data.

The model archive contains comprehensive model documentation, input files, source code, code version, output files, and output analysis approaches or software used to produce tables and figures for a particular publication. More ...
