Arcturus Flux Tower Measurements of Energy and Mass Exchange

Comprising flux tower measurements of energy and mass exchange between the surface and atmosphere using eddy covariance techniques. Data were processed with PyFluxPro (v3.4.7) to produce gap-filled products including Net Ecosystem Exchange (NEE), Gross Primary Productivity (GPP), and Ecosystem Respiration (ER). The measurements were collected from June 2011 to early 2014 at a station 48 km southeast of Emerald, Queensland.

Use Cases

• Analyze the partitioning of Net Ecosystem Exchange (NEE) into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER) to study carbon dynamics.
• Model the relationship between fluxes of heat, water vapor, methane, and carbon dioxide with supplementary measurements like temperature, humidity, and rainfall.
• Investigate the impact of land use types (lightly forested tussock grasslands vs. crop lands) on measured energy and mass exchange fluxes.
• Use gap-filled data products from PyFluxPro to validate or calibrate ecosystem models for semi-arid grassland and cropland environments.

Strengths

• Data processing uses the established PyFluxPro (v3.4.7) pipeline as described by Isaac et al. (2017), ensuring methodological consistency.
• The final product is gap-filled, providing a continuous time series for analysis of Net Ecosystem Exchange (NEE) and its components.
• Measurements cover a multi-year period from June 2011 to early 2014, capturing seasonal and interannual variability.
• The dataset includes a diverse set of measurements: fluxes of heat, water vapor, methane, and CO2, plus supplementary meteorological and soil data.

Limitations

• The temporal coverage is limited to a specific historical period (June 2011 to early 2014) and is not ongoing.
• The dataset's geographic scope is restricted to a single monitoring station in Queensland, Australia, limiting broader spatial analysis.
• Key structural metadata such as row count, column names, and file size are unknown, complicating assessment of dataset scale and specific variables.
