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 CD-04 CO2 Profiles, km 83 Tower Site, Tapajos National Forest. Data set prepared by S.D. Miller, M.L. Goulden, and H.R. da Rocha. This data set reports atmospheric carbon dioxide measured at 12 levels up to 64 m at the km 83 logged tower site in Tapajos National Forest, Brazil. Data were collected from June 2000 through March 2004 using an infra-red gas analyzer on the tower at 48 minute intervals. Data are provided in a single comma delimited file.
- LBA-ECO CD-04 Meteorological and Flux Data, km 83 Tower site, Tapajos National Forest. Data set prepared by S.D. Miller, M.L. Goulden, and H.R. da Rocha. This data set reports 30-minute, daily (24-hour), and monthly average flux tower measurements of carbon dioxide, water vapor, heat and meteorological variables in three comma delimited files.
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.
