Environmental Data Science & SystemsObjective: Provide data management and data analysis to the research community and policymakers, particularly in the areas of:• Carbon Cycle and Carbon Sequestration• Climatic Change Research• Atmospheric Radiation Measurements• Biogeochemistry of Terrestrial Ecosystems• Biodiversity
We provide access to value-added data and analysis tools used to: • Enable an objective assessment of anticipated and possible climate change, along
with the potential consequences of that change
• Improve the climate simulation capabilities of global climate models by improving the treatment of cloud and radiation physics
• Understand the complexity of the carbon cycle and the linkages to physical, biogeochemical & ecological processes, and human influences
• Discover and access a broad range of ecological and climate science data

ORNL DAAC: Roles in EOS
ORNL DAAC Overview for ESIP Carbon Cluster 2008-07-176
3. Regional and Global Studies
• Climate• Soils• Vegetation• Hydroclimatology
2. Validation of Remote Sensing Products
Four primary roles, supporting:
1. Field Campaigns• 6-9 year intensive
study of a region:•Amazon (LBA)•Northern Canada (BOREAS)•Southern Africa(SAFARI 2000)
BOREAS

’s from remote sensing DAACs Project Areas ->
Projects Data sets Granules 22 Projects; ~ 800 data sets; 400 GB Data sets are in multiple formats, often text Work with field investigators to clean up and
document data sets Median data set size is 500 KB
– 7 data sets are < 1 KB in total size– 5 data sets are > 10 GB in size– Approximately log normal distribution

What is Mercury (aka Beija Flor)?
Tool for harvesting, indexing, and searching geospatial-temporal metadata– Support for multiple metadata standards– Primary use is field data– Multiple, distinct sources of metadata, plus free text– Links to data ordering and data visualization tools
Adaptable for use in multiple projects– Same core code; mostly configuration differences
Fast query time, simple user interface Based on open source tools
– Lucene, SOLR, Spring, Apache, Tomcat, Hibernate
