LBA-ECO ND-07: Trace Gas Fluxes Under Multiple Land Uses in Brazil

Nine data files contain measurements of soil-atmosphere fluxes for carbon dioxide, carbon monoxide, nitrous oxide, and nitric oxide (CO2, CO, N2O, NO) collected near Brasília, Brazil from 1999 to 2004. Studies were conducted in pastures, agricultural areas, and natural cerrado and campo sujo vegetation under different fire and management regimes. This data provides relationships needed for modeling regional trace gas budgets.

Use Cases

• Modeling regional trace gas budgets based on flux measurements across land use types.
• Assessing the impact of fire frequency (e.g., biennial burning) on soil gas emissions.
• Comparing greenhouse gas fluxes between managed agricultural/pasture land and natural cerrado vegetation.
• Analyzing relationships between soil conditions (moisture, temperature) and trace gas emissions.

Strengths

• Data covers a multi-year time series from 1999 to 2004.
• Measurements span a variety of controlled land use and fire management conditions.
• Dataset is hosted on multiple authoritative platforms (Data.gov, NASA Earthdata), indicating established provenance.

Limitations

• Column names and exact row counts are not provided in the available metadata, limiting immediate usability.
• The 'last updated' metadata conflicts between sources (2005 vs. 2026), creating uncertainty about data currency.
• License is ambiguously specified as 'other-license-specified' without clear terms.
