The ORNL DAAC announces the release of a data set from the Carbon Dynamics science theme, a component of the LBA-ECO Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA).
LBA-ECO CD-15 LAI and Productivity Data, km 67, Tapajos National Forest: 2003-2004 . Data set prepared by M.H. Costa and W. Cohen. This data set provides mean leaf area index (LAI), dendrometry band measurements, and litterfall mass from samples collected at the km 67 research site, Tapajos National Forest, Para, Brazil. This site is situated in an area of primary tropical forest belonging to the municipality of Belterra, Para, Brazil. Samples were collected between December 2003 and November 2004.
LBA was an international research initiative under the leadership of Brazil. The project focused 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 was funded by NASA, focused 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? "
The ORNL DAAC is a NASA-funded data center archiving and distributing terrestrial ecology and biogeochemical dynamics data.
