Three New LBA-ECO CD08 Data Sets

Submitted by ORNL DAAC Staff on
The ORNL DAAC and the LBA DIS announce the release of three data sets associated with the LBA-ECO component of the Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA). These three data sets provide measurements of the structure and function of undisturbed tropical forest ecosystems in central Brazil.

LBA-ECO CD-08 Coarse Wood Litter Respiration and Decomposition, Manaus, Brazil. Data set prepared by Jeffrey Q. Chambers, J.P. Schimel, Antonio D. Nobre, Niro Higuchi, L.V. Ferreira, John M. Melack, and Susan E. Trumbore. This data set provides coarse wood density, moisture content, and respiration and decomposition rates for Central Amazon forests near Manaus Brazil measured during 1996 and 1997.

LBA-ECO CD-08 Tropical Forest Ecosystem Respiration, Manaus, Brazil. Data set prepared by Jeffrey Q. Chambers, Edgard S. Ttribuzy, Ligia C. Toledo, Bianca F. Cripim, Niro Higuchi, J.dos Santos, A.C. Arujo, Bart Kruijt, Antonio D. Nobre, and Susan E. Trumbore. This data set describes measurements made for leaf respiration, live wood (tree stem) respiration, and soil respiration along with additional environmental factors over 2000-2001 in a Central Amazon terra firme forest near Manaus.

LBA-ECO CD-08 Tree Inventory Data, Ducke Reserve, Manaus, Brazil: 1999. Data set prepared by Jeffrey Q. Chambers, J. dos Santos, R.J. Ribeiro, and Niro Hiuchi. This data set provides provides the common names, diameters, and calculated tree masses for almost 3,000 trees on a 5-hectare plot located in the Ducke Reserve near Manaus, Brazil in the Central Amazon that were inventoried in 1999.

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.
