Description
LBA-ECO TG-07 reports trace gas fluxes of methane, nitrous oxide, nitric oxide, and carbon dioxide from soils in the Tapajos National Forest, Brazil. The dataset was collected to test the effects of induced root mortality on soil-atmosphere gas exchange over one year. It also includes measurements of root mass, carbon content, soil nitrogen, nitrification, and moisture content.
Use Cases
[Modeling soil carbon and nitrogen cycling] based on [measurements of CO2, N2O, NO, CH4 fluxes and soil nitrogen content]
[Analyzing the temporal impact of root mortality on greenhouse gas emissions] based on [weekly and monthly flux measurements over one year following trenching treatment]
[Studying links between belowground biomass and soil gas production] based on [concurrent data for root mass and trace gas fluxes]
[Assessing soil moisture effects on gas flux rates in a tropical forest] based on [provided soil moisture content data]
Strengths
Contains detailed, multi-gas flux measurements (CH4, N2O, NO, CO2) alongside related soil and root variables
Provides high temporal resolution with weekly measurements for ten weeks post-treatment and monthly data for a full year
Dataset is part of the NASA LBA-ECO project, indicating a structured scientific collection effort
Limitations
Key metadata such as row count, specific column names, and file sizes are unavailable across all sources
Conflicting last-updated dates (2001 vs. 2026) create uncertainty about data currency and potential revisions
Documentation gaps exist, as the exact structure of the five comma-delimited files is not described
Provenance
Source
National Aeronautics and Space Administration (NASA)
Collection Method
Field measurements from a controlled trenching experiment isolating soil blocks to 1m depth to induce root mortality.
Time Range
One year following the trenching treatment.
