The ORNL DAAC announces the release of a data set associated with the Pre-LBA data compilation component of the Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA), which focused on providing data collected in Amazonia during the 20 years prior to 1998. These data were originally distributed on a three volume CDROM set, but are now being archived as 12 individual data sets.
Pre-LBA RADAMBrasil Data. Data set prepared by Paul A. Lefebvre. This data set contains soil descriptions for 1,153 soil pits distributed throughout Brazilian Amazonia, which were described and sampled by horizon and analyzed for texture and chemical composition.
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.
