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-03 Mesoscale Meteorological Data, Santarem Region, Para, Brazil: 1998-2006 Data set prepared by David R. Fitzjarrald, Ricardo K. Sakai, and Osvaldo Luiz Leal deMoraes. This data set reports meteorological data from the Santarem region of Para, Brazil, collected at eight stations for 2002-2005 and at some of the stations for as long as 1998-2006. Measurements include air temperature and pressure, wind speed and direction, relative humidity, downward solar radiation, and at some stations, soil temperature and moisture.
- LBA-ECO CD-03 Cloud Base-Backscatter Data, km 67 Tower Site, Tapajos National Forest Data set prepared by Matthew J. Czikowsky. This data set reports 30 minute average cloud base and backscatter profile data from the old-growth forest site located at the km 67 Eddy Flux Tower site, Tapajos National Forest, Santarem, Brazil. Ceilometer backscatter profiles were recorded at 30-m resolution up to 7500 m and measurement statistics were calculated. Three cloud base levels were calculated from the profiles. The ceilometer was operational for a sufficient amount of time to examine wet-dry seasonal variations in cloud cover fraction and cloud base height.
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.
