Two New LBA Data Sets

Submitted by ORNL DAAC Staff on

The ORNL DAAC and the LBA DIS announce the release of two data sets associated with the LBA-ECO component of the Large Scale Biosphere- Atmosphere Experiment in Amazonia (LBA).

"LBA-ECO LC-23 Vegetation Fire Data, Roraima, Brazil: 2003" contains Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Level-1B satellite imagery over controlled burns in the State of Roraima in Northern Brazil on January 19 and 28, 2003, plus simultaneously collected soil and near-surface air temperature profiles on January 28th. The ASTER imagery is provided in 14 zipped files containing HDF and HDF metadata file pairs, while the sample-based temperature profiles, one for the air the other for ground, are provided as comma separated ASCII files. The data set was prepared by Wilfrid Schroeder (University of Maryland), and Jeff Morisette (NASA).

"LBA-ECO LC-24 AVHRR Derived Fire Occurrence, 5-km Resolution, Amazonia: 2001" contains an ArcGIS ArcInfo grid (provided in e00 and ASCII formats) which provides the number of hot spots detected across the legal Amazon Basin at 5 km resolution by the Advanced Very High Resolution Radiometer (AVHRR) sensor on NOAA 12, 14, 15, 16, 17, and 18 satellites during calendar year 2001. The data set was prepared by Eugenio Arima (Hobart and William Smith Colleges).

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.
