ORNL DAAC Product Overview
PLACE HOLDER - PAGE TO BE WRITTEN
The goal of the EOS Validation Program is the comprehensive assessment of all
EOS science data products. 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. These data are
unique in having ground-based observations coincident with satellite data. In
addition, this information is useful to develop, calibrate, and validate
ecosystem models.
Data are available from the following NASA-funded Projects:
and through the following resources:
Regional and global biogeochemical dynamics data can be used to improve
our understanding of the structure and function of various ecosystems;
to enable prediction across spatial and temporal scales; and to
parameterize and validate terrestrial ecosystem models.
The ORNL DAAC compiles, archives, and distributes more than 150 products:
- Climate Collections
- Hydroclimatology Collections
- ISLSCP II Project
- Net Primary Productivity (NPP)
- River Discharge (RIVDIS)
- Russian Land Cover (RLC)
- Soil Collections
- Vegetation Collections
- Vegetation-Ecosystem Modeling (VEMAP)
Archiving environmental numeric data model products has become recognized as a vital research practice because it improves our ability to reproduce results, to perform additional analyses, and to synthesize results while investigating new hypotheses.
The ORNL DAAC compiles, archives, and distributes numerical models including the source code, input data, and output results in two tiers. The first tier supports the storage and retrieval of benchmark model versions, and the second teir supports the association of published research results with specific model implementations. Model products include:
- Biogeochemical process models
- Biosphere simulation models
- Ecosystem process and response models
- Land surface models
- Scaleable vegetation models
The following Data Tools are available to assist users is locating and working with our data, not all products are availabe in all tools:
