The Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA) is an international research project led by Brazil. NASA currently contributes to two components of the LBA program. One deals with the ecology of the region and the other deals with the hydrologic cycle. NASA's Land Surface Hydrology Program official incorporation into the large scale Biosphere-Atmosphere Experiment in Amazonia (LBA) is currently in review. The world's tropical forests are under major stress of conversion to various forms of land use. The implications this might have on regional and global climate, are not well known. Spaceborne remote sensing capabilities will help to define the basin scale forcing functions, and determine how the basin functions as a regional entity. At this website, provided will be information on radiative fluxes that are necessary to advance the understanding of the role of water in land-atmosphere interactions and for evaluation of land surface parametrizations. Developed will be improved inference techniques that take into account deforestation in Rondonia and information on biomass burning in the Amazon Basin.
