Lauder Grassland Carbon Flux Measurements From FLUXNET Tower

FLUXNET Release 2026_r1 provides processed eddy covariance flux tower measurements for energy and mass exchange between a grassland surface and the atmosphere. The data were processed using the ONEFlux software as per Pastorello et al. (2020) and produced as part of the FLUXNET Shuttle project. This release from April 2026 contains gap-filled products including Net Ecosystem Exchange partitioned into Gross Primary Productivity and Ecosystem Respiration.

Use Cases

• Modeling Net Ecosystem Exchange (NEE) dynamics from half-hourly or hourly flux time-series data.
• Partitioning NEE into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER) components for carbon budget analysis.
• Validating national inventory assumptions for grassland carbon flux using site-specific NEE measurements.
• Analyzing the exchange of energy (e.g., latent and sensible heat) and mass (e.g., CO2, water vapor) between the surface and atmosphere.
• Studying micrometeorological processes in a Central Otago grassland using quality-controlled, gap-filled eddy covariance data.

Strengths

• Data processed using the standardized, peer-reviewed ONEFlux methodology described in Pastorello et al. (2020).
• Provides a final, gap-filled product for key carbon flux variables (NEE, GPP, ER).
• Measurements are from a single, well-characterized site adjacent to the NIWA Lauder atmospheric research station.

Limitations

• Data is from a single tower location, limiting geographic generalizability.
• Sample size and temporal coverage (start/end dates) are unspecified.
• The raw description does not specify the temporal resolution (e.g., half-hourly) or the full suite of measured variables.
