Data Sets: Large-scale Biosphere-Atmosphere Experiment in Amazonia (LBA)

Data collected in Amazonia during the last 20 years are available in the Pre-LBA 3-Volume CD-ROM set. These data sets may be ordered at the LBA website and include satellite imagery, micrometeorological observations, near-surface and upper-air atmospheric conditions, and surface biophysical and hydrological measurements.


The JERS-1 CD-ROMs contain data from the JERS-1 SAR Global Rain Forest Mapping Project, an international project led by the National Space Development Agency of Japan (NASDA) that maps the world’s rainforest regions to high resolution by using Synthetic Aperture Radar (SAR). In accordance with NASA’s Memorandum of Understanding with NASDA, the JERS-1 SAR CD-ROM data are available under the condition that the recipient must submit evidence of how it is used to NASDA and/or NASA, if requested.

LBA data is also available through the web-based search and retrieval system, Beija-flor and ORNL’s search and order system, Mercury.

More information about LBA data sets is available on the LBA web site and the CEOP data management web site.


LBA Data Sets

LBA-ECO CD-04 CO2 Profiles, 83 km Tower Site, Tapajos National Forest

Atmospheric carbon dioxide measured at 12 levels up to 64 m at the 83 km 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

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-ECO CD-03 Mesoscale Meteorological Data, Santarem Region, Para, Brazil: 1998-2006

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, 67 km Tower Site, Tapajos National Forest

30 minute average cloud base and backscatter profile data from the old-growth forest site located at the forest site located at the 67 km 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.
