Ashley Dene FLUXNET: Eddy Covariance Flux Data for Irrigated and Non-Irrigated Crops

Eddy covariance flux tower measurements from the Ashley Dene research station in Canterbury, New Zealand, processed using the ONEFlux software. The data track energy and mass exchange between the surface and atmosphere, including Net Ecosystem Exchange partitioned into Gross Primary Productivity and Ecosystem Respiration. This release is part of the FLUXNET Shuttle project, with research supported by New Zealand's Ministry of Business, Innovation and Employment and the New Zealand Agricultural Greenhouse Gas Research Centre.

Use Cases

• Modeling carbon sequestration dynamics based on Net Ecosystem Exchange (NEE), Gross Primary Productivity (GPP), and Ecosystem Respiration (ER) data.
• Comparing evapotranspiration and energy budgets between irrigated and non-irrigated agricultural systems.
• Analyzing the impact of land-use change from lucerne to dairy pasture on ecosystem gas exchange.
• Calibrating and validating earth system models for temperate agricultural regions using standardized FLUXNET data.

Strengths

• Data processed using the standardized ONEFlux pipeline as described in Pastorello et al. (2020), ensuring FLUXNET compatibility.
• Site provides a paired comparison for irrigated and non-irrigated treatments, offering controlled experimental data.
• Covers a land-use transition from lucerne (2015-2020) to rotationally grazed dairy pasture, capturing temporal dynamics.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect geographic bias inherent to a single research station in Canterbury, New Zealand.
