LBA-ECO ND-02: Soil CO2 Flux and Chemistry in Brazilian Forests and Pastures

Soil CO2 flux measurements and physical-chemical soil characterizations were collected monthly from 16 sites near Rio Branco, Acre, Brazil. The data cover pastures, secondary forests, and mature forests from June 1999 to January 2001, with litter mass collection extending into 2002. This dataset supports analysis of land-use impacts on soil respiration and carbon dynamics in the Amazon.

Use Cases

• Modeling soil carbon emissions based on land cover type and soil chemistry.
• Comparing soil respiration rates between mature forests, secondary forests, and pastures.
• Analyzing temporal trends in soil CO2 flux over a multi-year period.
• Correlating litter mass with soil respiration rates in forest ecosystems.

Strengths

• Provides monthly time-series data from 16 distinct field sites.
• Includes complementary data on soil chemistry and litter mass.
• Covers three distinct land cover types (pastures, secondary forests, mature forests) for comparison.

Limitations

• Column names and exact file structure are not specified in the provided metadata.
• Conflicting last-updated dates exist between platforms (2002 vs. 2026), suggesting metadata may be inconsistent.
• The dataset's size and row counts are unknown, limiting assessment of its scale.
