The ORNL DAAC and the LBA DIS announce the release of two data sets from the Land Use-Land Change teams, a component of the LBA-ECO Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA). Both of these data sets provide GeoTiff image files of the Brazilian Amazon.
- LBA-ECO LC-35 Landsat ETM+ Derived Active Fire Masks, Brazilian Amazon: 2001-2003. Data set prepared by W. Schroeder, E. Prins, L. Giglio, I. Csiszar, C. Schmidt, J. Morisette, and D. Morton. This data set provides active fire detection images and associated summary information derived from Landsat 7 Enhanced Thematic Mapper Plus (ETM+) images for various locations in Brazilian Amazonia during 2001-2003. There are 244 GeoTiff format files. ETM+ images were selected based on data quality, availability, as well as the occurrence of vegetation fires.
- LBA-ECO LC-07 JERS-1 SAR Wetlands Masks and Land Cover, Amazon Basin: 1995-1996. Data set prepared by L. Hess, J.M. Melack, E.M.L.M. Novo, C.C.F. Barbosa, and M. Gastil. This data set provides three Amazon Basin wetland image products: (1) a Central Amazon Wetlands Mask, (2) a Central Amazon Wetlands Vegetative-hydrologic Land Cover Map, and (3) an Amazon Basin Wetlands Mask. All three were derived from the Global Rain Forest Mapping Project (GRFM) dry and wet season mosaics (August-September 1995 and May-August 1996) of the Japanese Earth Resources Satellite-1 (JERS-1) Synthetic Aperture Radar (SAR) imagery data. There are 6 GeoTIFF image files with this data set.
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.
