The ORNL DAAC announces the release of three data sets 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 SMOKE, CLOUDS, AND RADIATION-BRAZIL (SCAR-B) DATA. Data set prepared by Volker W.J.H. Kirchhoff and Carlos A. Nobre. This data set contains meteorological data, reanalysis data, remote sensing images, and data on atmospheric composition collected during the Smoke, Clouds, and Radiation-Brazil (SCAR-B) experiment.
Pre-LBA CABARE MAPPED LAND SURFACE AND VEGETATION CHARACTERISTICS, RONDONIA, BRAZIL. Data set prepared by Regina Celia Dos Santos Alvala, Genevieve Jaubert, Ivan R. Wright, Joel Noihan, and Jean C. Calvet. This data set contains terrain elevation, and classification data for vegetation and soil in the Rondonia region.
Pre-LBA RONDONIA BOUNDARY LAYER EXPERIMENT (RBLE) DATA. Data set prepared by Gilberto Fisch, Edson Rocha, S. S.Souza, Alistair Culf, Carlos Nobre, Humberto Rocha, Roberto Lyra, A.C.L. Costa, V.N. Urbana, Jean C. Calvet, and Ivan Wright. This data set contains information about the atmospheric boundary layer (ABL) collected during three campaigns over forested and deforested areas in Ji-Parana, Rondonia.
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.
