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

ARM Archive Archive for the DOE Atmospheric

Radiation Measurement (ARM) research facility ARM research questions:

– (Cloud occurrence and radiative energy transfer are major sources of uncertainties in climate models)

– What happens to all of the sunlight energy?– How is light absorbed by clouds?– What does partly cloudy mean? Statistically? Spatially?– www.arm.gov

ARM Infrastructure Mission:– Obtaining continuous field measurements

3 fixed location – Providing data products that promote the advancement of

climate models Archive Mission:

– Store and distribute all data generated by ARM field operations to the research community

– Interact with the data generator and data user communities to ensure continued, long-term data usability

CDIAC Carbon Dioxide Information and

Analysis Center Primary climate change data & information analysis

center for DOE World Data Center for Atmospheric Trace Gases Diverse holdings

– Atmospheric CO2 concentration measurements– Other atmospheric gas measurements– Ameriflux data archive– DOE Ocean CO2 program– FACE Experiment data– Assessment of emissions and impacts

Extremely broad user community

Contact: Tom Boden ([email protected])


ORNL DAAC Distributed Active Archive Center for

Biogeochemical Dynamics– Part of the NASA Earth Observing System Data and

Information System (EOSDIS)– Nine other NASA EOSDIS Data Centers in different

disciplines, at other locations Holds and delivers data on NASA Field

campaigns, regional and global data for biogeochemistry, and satellite validation– Also manages site information for FLUXNET

Provides a range of tools for data discovery, data visualization, and data subsetting– Particular tools to make remote sensing data

accessible to field scientists

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

4. Model Code• Benchmark Models

•IBIS, BIOME-BGC, LSM• Manuscript Models

•PNeT, Century, Biome-BGC


’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



ORNL DAAC Mercury Holds metadata for ORNL DAAC archive Long Term Ecological Research Network

(LTER) holdings– LTER also indexing ORNL DAAC holdings

Organization of Biological Field Stations (OBFS) holdings

LP DAAC MODIS & Aster collections Metadata catalog for data sets held

elsewhere, but of community interest– Regional & Global Data– Land Validation
