Description
Tapajos National Forest in Para, Brazil, is the location for this dataset measuring soil-atmosphere trace gas fluxes. It reports methane, nitrous oxide, nitric oxide, and carbon dioxide fluxes alongside root mass, soil nitrogen, nitrification, and moisture data. The research was designed to test the effects of induced root mortality on gas fluxes over a one-year period.
Use Cases
Analyzing the temporal response of greenhouse gas fluxes to experimental root mortality based on weekly and monthly measurements.
Modeling relationships between soil moisture, nitrogen content, and trace gas emissions in a tropical forest.
Comparing root carbon content and biomass data against concurrent soil gas flux rates.
Studying the effects of trenching treatments on soil-atmosphere exchange over a one-year time series.
Strengths
Contains multi-gas flux measurements (CH4, N2O, NO, CO2) paired with complementary soil and root data.
Provides a year-long time series with high-frequency weekly measurements for ten weeks post-treatment.
Dataset is part of the NASA LBA-ECO project, indicating a structured scientific collection effort.
Limitations
Column names and exact row counts are not provided in the available metadata, limiting immediate usability.
Conflicting last-updated dates exist between platforms (2001 vs. 2026), creating uncertainty about data currency.
Documentation is described across five separate files, which may require assembly or reconciliation.
Provenance
Source
National Aeronautics and Space Administration (NASA) as part of the LBA-ECO project.
Collection Method
Field experiment inducing root mortality via trenching and root exclusion screening to 1 m depth, with subsequent gas flux measurements.
Time Range
One year following the trenching treatment.
Freshness
Last updated dates conflict: one source lists 2001-07-14, while others list 2026-04 10.
Geography
Tapajos National Forest, near km 83 on the Santarem-Cuiaba Highway, south of Santarem, Para, Brazil.
