Biogeochemical Dynamics - the ORNL DAAC
ORNL DAAC Home Page URL -
http://www-eosdis.ornl.gov
The Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center
(DAAC) for Biogeochemical Dynamics is an integral part of the nine NASA
Earth Observing Data and Information System (EOSDIS) DAACs. In general
terms, biogeochemical dynamics can be described as the biological and
chemical interactions among the elements that comprise the Earth system. The
DAAC is operated within the Environmental Sciences Division at ORNL with the
advantage of access to staff conducting research and assessments on
biogeochemical dynamics as related to global change issues. Data at the
ORNL DAAC are of interest to the global change research community, policy
makers, educators, and to the public at large.
Users may request information through the EOSDIS Wide Information Management
System (IMS), directly through the local ORNL DAAC IMS; or by contacting the
User Services Office.
Data Availability
-----------------
The ORNL DAAC currently archives and distributes data from CDIAC
and from the FIFE & OTTER research projects. Future data holdings
include information gathered from the BOREAS project. Additionally,
the ORNL DAAC is currently working with the FIFE Follow-on project
investigators to receive and distribute additional FIFE data.
A pilot project, coordinated with the International Geosphere Biosphere
Program (IGBP), has been initiated to develop a global terrestrial net
primary productivity reference database. Plans are also underway for
acquiring background data for an international Amazon Basin field
investigation. Additional information about our data holdings, both
current and future, are provided below.
CDIAC
-----
The Carbon Dioxide Information Analysis Center (CDIAC) provides information
related to atmospheric trace-gas concentrations and global climate change.
CDIAC is sponsored by the U.S. Department of Energy to support the Global
Change Research Program and is located at ORNL. The preponderance of the
data deal with historic and atmospheric carbon dioxide and methane
concentrations and historic weather and climate readings from throughout the
world. Thus, CDIAC data are relevant to the DAAC user community.
CDIAC datasets are maintained by CDIAC; however, the user community can
access these data through the EOSDIS System-Wide IMS as well as through the
ORNL DAAC IMS.
FIFE
----
The First ISLSCP (International Satellite Land Surface Climatology Project)
Field Experiment (FIFE) was conducted on the Konza Prairie located just
outside of Manhattan, Kansas, USA, during the summer of 1987 and 1989. The
FIFE project is part of NASA's plan to develop a physically-based approach
to the use of satellite remote-sensing systems. Project data include:
fluxes of heat, moisture, CO2 and radiation measured with surface and
airborne equipment; soil moisture data; atmospheric boundary layer data;
vegetative indices; surface radiance and biological data; and satellite
measurements: AVHRR, LANDSAT, SPOT, GOES.
FIFE tabular data are available on-line through the local ORNL DAAC IMS and
will be available through the System-Wide IMS shortly.
OTTER
-----
The purpose of the Oregon Transect Ecosystem Research (OTTER) Project was to
estimate major fluxes of carbon, nitrogen, and water in forest ecosystems
using an ecosystem-process model driven by remotely-sensed data. Study
sites included a coastal forest of western hemlock; a mid-elevation forest
of mature Douglas fir; and an inland forest of ponderosa. Meteorological
data and remotely-sensed measurements of foliar nitrogen and leaf area index
drove the model, while field measurements of monthly changes in canopy leaf
area, photosynthetic capacity, stomatal conductance, foliage biochemistry,
litterfall, and other components of plant production were used to validate
the model. Each site was instrumented for continuous measurement of surface
meteorology and monitored frequently for carbon exchange, nutrient cycling
rates, and water transport. ASAS, AVHRR, AVIRIS, TMS aircraft and satellite
measurements data were also compiled for the project.
OTTER tabular data are available on-line through the local ORNL DAAC IMS
and will be available through the System-Wide IMS shortly.
BOREAS
------
The Boreal Ecosystem-Atmosphere Study (BOREAS) was initiated in 1990 to
investigate the interactions between the boreal forest biome and the
atmosphere. Surface, airborne, and satellite based observations are being
used to develop techniques to measure biological and physical processes and
conditions that govern the exchanges of energy, water, heat, carbon, and
trace gases between boreal forest ecosystems and the atmosphere,
particularly those processes that may be sensitive to global change.
Remote-sensing techniques, along with field measurements, are being used to
develop and test models and algorithms in order to transfer the
understanding of processes from the local to regional scale. The
investigation is being conducted in the boreal forest of Canada and is
scheduled for completion in 1997. Intensive Field Campaigns (IFCs) were
conducted throughout the summer of 1994.
BOREAS data will be transferred to the ORNL DAAC as the investigators
complete documentation, quality assurance, and within-project integration
and verification.
Net Primary Productivity (NPP)
-----------------------------
A global terrestrial Net Primary Production (NPP) reference database is
being compiled by the ORNL DAAC in coordination with the International
Geosphere Biosphere Program. Field measurements from worldwide sites
provide parameterization and validation data needed in support of modeling
global primary production and other applications. Currently there are
detailed biomass dynamics, climate, and site data for 13 grassland
representing 6 biomes in the database with over 150 site-year-treatment
combinations and an average of 30 years of climate data for each site. An
important component of the database is an abstract of each site with
investigator contact information and a list of key references for each site.
Pending final approval from the Principal Investigators (PI's), release
to the overall user community is expected soon. A notification will be
posted to the appropriate USENET groups/Listservs upon release.
World Wide Web Home Page
------------------------
The ORNL DAAC World Wide Web (WWW) Home Page contains detailed information
regarding the ORNL DAAC, EOSDIS, data holdings, and links to many other
relevant sources of information. The ORNL Home Page can be accessed at the
following location:
http://www-eosdis.ornl.gov
Accessing ORNL Data
-------------------
Users can search and order data through the EOSDIS System-Wide IMS linked to
all of the DAAC's or through the ORNL DAAC IMS, which is tailored to meet
needs of users seeking ecologically-related data. In order to access either
IMS systems via a Graphical User Interface (GUI), you must be using either a
workstation or a PC/MAC running X-terminal emulation software. You may
however, access the System-Wide IMS via a Character-Based Interface (ChUI)
if you do not meet the necessary system requirements. The telnet address
for the System-Wide IMS ChUI is the same as listed below for the GUI.
To access the EOSDIS System-Wide IMS: telnet eosims.ornl.gov 12345
To access the ORNL DAAC IMS: telnet ornlims.ornl.gov 6493
Also, the ORNL DAAC is putting the finishing touches on BIOME, the
Biogeochemical Information Ordering Management Environment. Via this new
World Wide Web (WWW) based interface, a user can both search and order ORNL
DAAC held data. An announcement of its release will be made on this
newsgroup.
Data are available from the ORNL DAAC on a wide variety of media formats.
Both OTTER and FIFE data are currently available on a 5 volume CD-ROM set.
Please contact the ORNL DAAC User Services Office for additional information.
