Atmospheric Radiation Measurements

The ARM Climate Research Facility, a DOE scientific user facility, provides the climate research community with strategically located in situ and remote sensing observatories designed to improve the understanding and representation, in climate and earth system models, of clouds and aerosols as well as their interactions and coupling with the Earth’s surface.

Carbon Dioxide Information Analysis Center (CDIAC)

The Carbon Dioxide Information Analysis Center (CDIAC) serves the climate change-related data and information needs of users worldwide. CDIAC's holdings - all of which are available free of charge - include estimates of carbon dioxide emissions from fossil-fuel consumption and land-use changes; records of atmospheric concentrations of carbon dioxide and other radiatively active trace gases; carbon cycle and terrestrial carbon management datasets and analyses; global and regional climate data and time series; and analyses of land-cover/land-use change.

Next-Generation Ecosystem Experiments - Arctic

NGEE Arctic logoThe mission of the NGEE-Arctic project is to improve climate model predictions through advanced understanding of coupled processes in Arctic terrestrial ecosystems. Increasing our confidence in climate projections for high-latitude regions of the world will require a coordinated set of investigations that target improved process understanding and model representation of important ecosystem-climate feedbacks. NGEE Arctic seeks to address this challenge by quantifying the physical, chemical, and biological behavior of terrestrial ecosystems in Alaska. Data sets are available at

Spruce and Peatland Responses Under Changing Environments

The SPRUCE experiment is an experiment to assess the response of northern peatland ecosystems to increases in temperature and exposures to elevated atmospheric CO2 concentrations.  The experimental work in the 8.1-ha S1 bog is a climate change manipulation focusing on the combined responses to multiple levels of warming at ambient or elevated CO2 (eCO2) levels. Data sets are available at

Free Air CO2 Enrichment (FACE) Data Management System

The goal of the Free-Air CO2 Enrichment (FACE) project is to understand how forests will be affected by CO2 enrichment of the atmosphere and the feedbacks from the forest to the atmosphere. This goal is being approached by measuring the integrated response of an intact forest ecosystem, with a focus on stand-level mechanisms. These projects were part of the CO2 research network fostered by the Global Change and Terrestrial Ecosystemscore project of the International Geosphere-Biosphere Programme. Results from the experiment contribute to the Terrestrial Ecosystem Response to Atmospheric and Climatic Change (TERACC) project, a 5-year initiative integrating experimental data and global change modeling.

Distribute Active Archive Center for Biogeochemical Dynamics (DAAC)

The Oak Ridge National Laboratory Distributed Active Archive Center (ORNL DAAC) for Biogeochemical Dynamics is one of the NASA Earth Observing System Data and Information System (EOSDIS) data centers managed by the Earth Science Data and Information System (ESDIS) Project, which is responsible for providing scientific and other users access to data from NASA's Earth Science Missions. The ORNL DAAC is responsible for data archival, product development and distribution, and user support for biogeochemical and ecological data and models.

Mercury: Distributed Metadata Management, Data Discovery and Access System

ORNL powered by mercuryMercury is a set of tools for harvesting, searching, and retrieving metadata and data. Mercury harvests metadata and key data from contributing project servers distributed around the world and builds a centralized virtual index. The Mercury search interface provides a single portal to very quickly search for data and information contained in disparate data management systems, each of which may use different metadata formats. The search interface allows users to perform a variety of fielded, spatial, and temporal searches across these metadata sources. This centralized repository of metadata with distributed data sources provides extremely fast search results to the user, while allowing data providers to advertise and distribute their data and maintain complete control and ownership of that data. Mercury is developed and managed at Oak Ridge National Laboratory and is currently being funded by three federal agencies, including NASA, USGS and DOE. It provides access to more than 300,000 Bio-geo-chemical and ecological data; 30,000 scientists use it each month.
