LBA-ECO CD-06: CO2 Exchange and Forest Biomass in the Amazon Basin (2004-2007)

LBA-ECO CD-06 provides two distinct but related datasets from the Large-Scale Biosphere-Atmosphere Experiment in Amazonia. The first contains measurements of carbon dioxide flux, gas transfer velocity, and partial pressure from 75 river and stream sites across the Amazon system between July 2004 and January 2007. The second dataset includes forest biomass measurements, specifically leaf area index, dendrometry, and litterfall mass, collected at the km 67 site in Tapajós National Forest, Brazil, during 2004.

Use Cases

• Modeling CO2 outgassing from Amazonian rivers based on flux rates and gas transfer velocity measurements.
• Analyzing the relationship between river chemistry (pH, sediment load) and carbon dioxide partial pressures across different flow conditions.
• Estimating forest canopy dynamics and productivity using leaf area index and litterfall mass time series.
• Calibrating remote sensing products for tropical forest biomass with ground-based dendrometry measurements.
• Assessing spatial variability in carbon exchange across the spectrum of chemical characteristics in the Amazon basin.

Strengths

• Covers a wide spatial range with measurements from 75 distinct river and stream sites.
• Includes temporal data across multiple fieldwork campaigns from 2004 to 2007, capturing low to high flow conditions.
• Provides complementary terrestrial data from a well-characterized primary forest research site with detailed plot and transect design.

Limitations

• Column names and specific data structure are not provided in the available metadata.
• The relationship between the river chemistry dataset and the forest biomass dataset is not explicitly described.
• Metadata indicates an 'other-license-specified' license, but the specific terms are not stated.
