The ORNL DAAC announces the release of nine Carbon Dynamics data sets associated with the LBA-ECO component of the Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA).
These Carbon dynamics studies involved the quantification of the carbon pools in vegetation and the rates of carbon exchange among the atmosphere, vegetation, and soils. Ecosystem carbon balance was investigated in a primary tropical forest in central Amazonia using an approach that integrated long-term eddy covariance flux measurements with comprehensive ecological characterization methods. These data are applicable for the investigation of the way in which these rates may be altered by natural and human disturbances.
Studies took place in the old-growth upland forest at the Para Western (Santarem) - km 67, Primary Forest Tower site. This site is in the Tapajos National Forest located in north central Brazil.

LBA is an international research initiative under the leadership of Brazil. The project focuses on the climatological, ecological, biogeochemical, and hydrological functions of Amazonia; the impact of land use change on these functions; and the interactions between Amazonia and the Earth system. The LBA-ECO component, which is funded by NASA, focuses on the question: "How do tropical forest conversion, regrowth, and selective logging influence carbon storage, nutrient dynamics, trace gas fluxes, and the prospect for sustainable land use in Amazonia?"
See the LBA Project page for further information about the study and to access associated data and documentation maintained by the ORNL DAAC.
