The AmeriFlux US-ARM dataset provides carbon flux and greenhouse gas measurements from a cropland site in Lamont, Oklahoma, part of the Southern Great Plains. It was contributed by author Margaret Torn from the Lawrence Berkeley National Laboratory. The data likely includes continuous measurements of CO2, CH4, CO, and N2O mixing ratios, as well as isotopic 13CO2, from a central facility tower over fields of winter wheat, corn, soy, and alfalfa.
Use Cases
- Modeling net ecosystem exchange (NEE) based on carbon flux data.
- Analyzing greenhouse gas mixing ratios (CO2, CH4, CO, N2O) for atmospheric studies.
- Studying carbon isotope (13CO2) signatures to trace carbon source processes.
- Investigating micrometeorology and turbulence using sonic anemometer data from 25m and 60m heights.
Strengths
- Includes precise, continuous measurements of multiple greenhouse gases (CO2, CH4, CO, N2O).
- Contains isotopic ratio data for 13CO2, which can provide insights into carbon source processes.
- Features multi-height wind measurements from sonic anemometers at 4m, 25m, and 60m.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file size are unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
