Five ND-02 Ecosystem Data Sets Released from LBA-ECO
The ORNL DAAC and the LBA DIS announce the release of five data sets
associated with the LBA-ECO component of the Large Scale Biosphere-
Atmosphere Experiment in Amazonia (LBA).
Four of the data sets report soil trace gas fluxes of carbon dioxide (CO2),
methane (CH4), nitrous oxide (N2O), and nitric oxide (NO) from undisturbed
forest, secondary growth forest, and agricultural soil sites under control
and various experimental conditions. The fifth data set reports secondary
forest biophysical parameters measured in a forest fertilization experiment.

LBA-ECO ND-02 Agricultural and Secondary Forest Soil Trace Gas Flux, Para: 2001-2004.
Data set prepared by E.A. Davidson, T.D. de Abreu Sa, C.J.R. de Carvalho, and R.O. Figueiredo.
This data set reports the results of a study that measures soil emissions of trace gases
throughout an entire cropping cycle in slash-and-burn and chop-and-mulch prepared
agricultural fields from 2001 through 2004.
-
LBA-ECO ND-02 Soil Trace Gas Fluxes in Eastern Amazonia, Para, Brazil: 1999-2003.
Data set prepared by E.A. Davidson, C.J.R. de Carvalho, and R.O. Figueiredo.
This data set reports the results of a study to quantify the effects of moisture
and substrate availability on soil trace gas fluxes in a regrowth forest in Eastern
Amazonia, Apeu, Para, Brazil, from 1999 through 2003.
-
LBA-ECO ND-02 Trace Gas Flux from Forest Soil, Para, Brazil: 1999-2001.
Data set prepared by E.A. Davidson, C.J.R. de Carvalho, I.C.G. Vieira, and
R.O. Figueiredo. This data set contains soil emissions of trace gases
measured in plots of a secondary-growth forest fertilization experiment
located 6.5-km northwest of the town of Paragominas, Para, Brazil during 1999
through 2001.
-
LBA-ECO ND-02 Soil Gas Flux, Rainfall Exclusion, km 67, Tapajos National
Forest.
Data set prepared by E.A. Davidson, C.J.R. de Carvalho, and R.O. Figueiredo.
This data set reports the results of a rainfall exclusion experiment on trace
gas emissions from the km 67 flux tower site in Tapajos National Forest (Flona-
Tapajos) from December 1999 through April 2005.
-
LBA-ECO ND-02 Secondary Forest Tree Heights and Diameters, Para, Brazil: 1995-2005.
Data set prepared by E.A. Davidson, C.J.R. de Carvalho, I.C.G. Vieira, R.O. Figueiredo, P. R. Moutinho,
F.Y. Ishida, M.T.P. dos Santos, J.B. Guerrero, K. Kalif, and R.T. Saba. This data
set provides tree diameters and heights measured from 1999 through 2005 in plots
of a secondary-growth forest fertilization experiment located 6.5-km northwest of
the town of Parogominas, Para, Brazil.
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?"

documentation maintained by the ORNL DAAC.
The ORNL DAAC
is a NASA-funded data center
archiving and distributing terrestrial ecology and biogeochemical
dynamics data.
