Longreach Mitchell Grass FLUXNET 2026: Eddy Covariance Flux Tower Data

Mid-2018 onward flux tower measurements from a Mitchell Grass Rangelands site near Longreach, Queensland. The data set contains processed and gap-filled estimates of Net Ecosystem Exchange (NEE), Gross Primary Productivity (GPP), and Ecosystem Respiration (ER) produced using PyFluxPro and ONEFlux software. This release is part of the FLUXNET Shuttle project and was funded by the Australian Government.

Use Cases

• Modeling carbon sequestration dynamics based on Net Ecosystem Exchange (NEE) data.
• Partitioning ecosystem carbon flows based on Gross Primary Productivity (GPP) and Ecosystem Respiration (ER) estimates.
• Studying water and energy fluxes in a semi-arid rangeland environment.
• Validating remote sensing products and land surface models with ground-truth eddy covariance measurements.

Strengths

• Data processed using established PyFluxPro and ONEFlux methodologies as cited in the description.
• Covers a significant land area, with the rangeland region spanning approximately 47 million hectares.
• Provides a final, gap-filled product for key carbon flux variables (NEE, GPP, ER).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and temporal resolution are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to a single site in western Queensland.
