FIFE Soil Gas Fluxes from 1987 Core Samples

Kansas prairie soil gas flux data from the FIFE experiment measures daily rates of denitrification, nitrous oxide, and carbon dioxide. Measurements were taken at 10 sites on four dates in 1987 using an intact extracted core technique. The dataset was produced by ORNL_CLOUD to study scaling relationships between gas fluxes, soil moisture, and plant productivity.

Use Cases

• Analyzing relationships between daily denitrification flux rates and soil moisture measurements.
• Scaling annual nitrous oxide fluxes using large-area plant productivity data from SPOT images.
• Comparing in situ carbon dioxide flux with fluxes from cores amended with water or water plus nitrate.
• Evaluating denitrification in the context of prairie ecosystem ecology as presented in Groffman et al. (1992).

Strengths

• Data is derived from a controlled experiment with a defined methodology: intact extracted core technique.
• Provides measurements from 10 distinct sites across four sampling dates, offering spatial and temporal context.
• Analysis is supported by peer-reviewed publication (Groffman et al., 1992).

Limitations

• Key metadata such as row count, column names, and exact file size are unavailable from all sources.
• Sources conflict on the last updated date: one states 2026-03-12, another states 1987-06 28.
• The dataset is limited to a single year (1987) and a specific geographic study area.
