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

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
