Data Fair Use

We encourage the download and use of these data. We also encourage your feedback if you have questions or comments on the dataset, including issues with data quality. The following paragraph on data use is taken from the LBA-ECO website (http://www.lbaeco.org/lbaeco/data/data_use.htm) - you can find more information on the LBA-ECO data policy there.

"Where data are used for modeling or integrating studies, the scientist collecting the data will be credited appropriately, either by co-authorship or by citation. The data collectors should be informed of publication plans well in advance of submission of a paper, given an opportunity to read the manuscript, and be offered co-authorship. In cases where data from other investigators are a minor contribution to a paper, the data should be referenced by a citation. Users of the data will always have to state the source of the data."

DATA SETS

Micrometeorology

Km 83 Meteorological and Flux Data, Measured: (July 1, 2000-Mar 11, 2004, ~8 MBytes, posted March 30, 2007)

Over 3.5 years of measured and calculated quantities at the km 83 tower site related to site meteorology, fluxes of momentum, heat, water vapor, and carbon dioxide, and the storage of carbon dioxide in the air column beneath the flux sensors. The data are not gap-filled, and net ecosystem exchange has not been filtered for calm nighttime periods.  

Km 83 Gap-Filled Data (July 1, 2000-Mar 11, 2004, preliminary~23 MBytes, posted March 2005)

Three and one half years of half-hourly meteorologcial and flux data that have been gap-filled as described in Miller et al (2004). Time period covers most all of the measurements for this flux tower. 140 columns, including solar radiation, net radiation, air temperature, wind speed, precipitation, wind speed profile above canopy, temperature profile between 64 and 2 meters, soil temperature profile, soil moisture profile, soil heat flux, outgoing solar radiation, incoming longwave radiation, outgoing longwave radiation, PAR, sensible heat flux, latent heat flux, friction velocity, CO2 concentration, turbulent co2 flux from closed path sensor, turbulent co2 flux from open path sensor, co2 storage flux, NEE filtered and unfiltered. Also includes CO2 and H2O profiles at 12 levels between 0.1 and 64 meters.

Biometric Survey Data

Km 83 March 2000 Biometric Survey:
Measurements of DBH for trees over 35 cm in 18 ha block (300 m N-S, 600 m E-W) east of the eddy flux tower.
 

Leaf Litter Data

Km 83 Leaf Litter (LAI) Data:
Measurements of LAI using leaf litter data in 18 ha block (300 m N-S, 600 m E-W) east of the eddy flux tower.
 

Dendrometer Data

Km 83 Dendrometer Data:
Dendrometer measurements in 18 ha block (300 m N-S, 600 m E-W) east of the eddy flux tower, beginning in July 2000.
 

Post-Logging Gap Map

Km 83 Gap Map:
Map of gaps created by selective logging between September and December 2001 at Tapajos National Forest, km 83.  Map includes18 ha block (300 m N-S, 600 m E-W) east of the eddy flux tower.
 

Soil Respiration Chamber Data

Km 83 Soil Respiration Chamber Data:
15 automated soil respiration chambers were installed in August 2001 in an intact area of forest at Tapajos National Forest, km 83.  In February 2002, following selective logging, 5 of the chambers were relocated to forest gaps opened up by the logging.  All of the chambers are located east of the eddy flux tower.
 

Leaf Level Photosynthesis and Respiration Data

Km 83 Leaf Level Photosynthesis and Respiration, and Soil Repsiration Measurements:
Measurements of leaf photosynthesis and respiration and soil respiration using the LI6200 during Summer 2001 in 18 ha block (300 m N-S, 600 m E-W) east of the eddy flux tower.
