Nebraska data from the AmeriFlux network for an irrigated maize-soybean rotation field at the University of Nebraska Agricultural Research and Development Center near Mead. The site has a long-term management history, including a tillage operation in 2001 followed by continuous no-till. The dataset was contributed by author Andy Suyker from the University of Nebraska–Lincoln.
Use Cases
- Modeling net ecosystem exchange (NEE) of CO2 for irrigated croplands based on the site's carbon flux measurement focus.
- Studying the impact of long-term no-till management on carbon sequestration based on the described field management history.
- Analyzing crop rotation effects on seasonal carbon and water fluxes based on the maize-soybean rotation described.
- Calibrating and validating process-based ecosystem models for the U.S. Midwest based on the site's geographic and crop system details.
Strengths
- Data is part of the standardized AmeriFlux network, which suggests consistent processing and quality control.
- Site description provides specific management history, including a 10-year pre-study rotation and a known tillage event in 2001.
- Field is part of a trio of research sites located within 1.6 km, enabling potential comparative studies.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count, temporal coverage, and file formats are unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
Provenance
- Source
- AmeriFlux network, contributed by Andy Suyker, University of Nebraska–Lincoln.
- Collection Method
- Likely collected via eddy covariance towers at the field site.
- Geography
