The ORNL DAAC and the LBA DIS announce the release of four data sets associated with the LBA-ECO component of the Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA). These data sets are from the Carbon Dynamics Team and report research results from the km 83 logged forest tower site, Tapajos National Forest, Brazil.
- LBA-ECO CD-04 Leaf Area Index, km 83 Tower Site, Tapajos National Forest, Brazil . Data set prepared by M. Figueira, C.A.D. de Sousa, M. Menton, R.N. Juarez, H.R. da Rocha, S.D. Miller, and M.L. Goulden. This data set reports on leaf area determination utilizing a computer scanner and image processing software.
- LBA-ECO CD-04 Biomass Survey, km 83 Tower Site, Tapajos National Forest, Brazil . Data set prepared by M. Menton, M. Figueira, C.A.D. de Sousa, S.D. Miller, H.R. da Rocha, and M.L.Goulden. This data set contains the results of a biometric tree survey of a 19.25 ha area adjacent to the eddy flux tower at the km 83 logged forest tower site.
- LBA-ECO CD-04 Dendrometry, km 83 Tower Site, Tapajos National Forest, Brazil . Data set prepared by M. Figueira, S.D. Miller, C.A.D. de Sousa, M. Menton, A.R. Maia, da Rocha, and M.L.Goulden. Dendrometry measurements are reported for a study conducted over a four year period following the implementation of a reduced impact logging management regime.
- LBA-ECO CD-04 Leaf Litter Data, km 83 Tower Site, Tapajos National Forest, Brazil . Data set prepared by M. Figueira, C.A.D. de Sousa, M. Menton, R.N. Juarez, H.R. da Rocha, S.D. Miller, and M.L.Goulden. This data set reports on above-ground litter productivity measured in a 18 ha plot adjacent to the eddy flux tower at the km 83 site.
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.
The ORNL DAAC is a NASA-funded data center archiving and distributing terrestrial ecology and biogeochemical dynamics data. The LBA Data and Information System (LBA-DIS) has been developed by INPE with NASA's participation.
