Ashley Dene Dry FLUXNET Release 2026_r1

Flux tower measurements from 2015/16 onward at a research dairy station on the Mid-Canterbury plains, South Island, New Zealand. The data contain processed and gap-filled estimates of Net Ecosystem Exchange (NEE), Gross Primary Productivity (GPP), and Ecosystem Respiration (ER) from a site growing lucerne until 2020, then converted to dairy pasture. This release was produced as part of the FLUXNET Shuttle project using the ONEFlux software.

Use Cases

• Modeling carbon sequestration and greenhouse gas budgets in rotational grazing systems based on NEE, GPP, and ER data.
• Analyzing the impact of irrigation on ecosystem productivity and respiration in agricultural landscapes.
• Calibrating and validating land surface models using standardized, gap-filled eddy covariance flux data.
• Studying seasonal and interannual variability in energy and mass exchange for a temperate pasture site.

Strengths

• Data processed using the standardized ONEFlux pipeline as described in Pastorello et al. (2020), ensuring methodological consistency with FLUXNET.
• Provides a gap-filled final product for key carbon flux variables (NEE, GPP, ER), reducing data gaps for analysis.
• Covers a land-use transition from lucerne to dairy pasture, offering insights into management change effects.

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 for large-scale modeling.
• Data may reflect geographic and temporal bias inherent to a single research site in New Zealand.
