The Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA) is an international research initiative led by Brazil. LBA is designed to create the new knowledge needed to understand the climatological, ecological, biogeochemical, and hydrological functioning of Amazonia, the impact of land use change on these functions, and the interactions between Amazonia and the Earth system.

To access LBA project information (e.g., the science plan, contact information such as phone numbers and email addresses, LBA meeting announcements), please check this mirrored LBA homepage. The original LBA homepage is located and maintained by CPTEC at INPE in Brazil.

The LBA Project encompasses several scientific disciplines, or components. The LBA-Ecology component 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?" The ORNL DAAC will archive data gathered from the LBA-Ecology component of LBA. For additional information on this component of LBA, access the LBA-Ecology project page at Goddard Space Flight Center.

ORNL is offering LBA data through the web-based search and retrieval system, Beija-flor. Beija-flor (Portuguese for "flower kisser," or hummingbird) is LBA's name for its version of ORNL's search and order system, Mercury. Historic LBA-related data sets have already been registered into Beija-flor. Additional LBA-related data sets and Amazon Basin subsets of global data collections are currently being added to the Beija-flor index. LBA investigators are making their data available to other researchers and users through Beija-flor by using the LBA Metadata Editor.
