Soil CO2 Flux Data from Brazilian Amazon Tower Site

Fifteen automated chambers measured carbon dioxide flux from logged forest soils near an eddy flux tower in the Tapajós National Forest, Brazil. NASA collected this data over a 73-day period from December 2001 to March 2002. The dataset provides direct measurements of soil respiration in a primary tropical forest environment.

Use Cases

• Analyzing diurnal and seasonal patterns of soil CO2 respiration using time-series measurements.
• Correlating soil carbon flux with above-canopy eddy covariance tower data from the same site.
• Modeling the impact of selective logging on soil carbon dynamics in primary Amazonian forest.
• Calibrating or validating terrestrial ecosystem models for tropical forest carbon budgets.

Strengths

• Data collected via 15 automated soil chambers, providing spatial replication.
• Measurements cover a specific 73-day period from December 19, 2001 to March 1, 2002.
• Dataset originates from NASA, indicating a standardized collection protocol.

Limitations

• Exact column names, row count, and file size are not specified in any source.
• Sources conflict on the last updated date: one lists 2002-03-01, another lists 2026-03 -13.
• Temporal coverage is limited to a short, non-continuous period of less than three months.
