Hoh Xil Alpine Steppe Carbon Flux Data from 2022 to 2024

Eddy covariance measurements from the Hoh Xil alpine steppe provide half-hourly data on ecosystem productivity, air temperature, and soil conditions. The dataset covers a three-year period from 2022 to 2024 and has been processed using internationally accepted standard methods. Author Linfeng Zhang published the 4.9 MB dataset under a CC-BY-4.0 license on figshare.

Use Cases

• Modeling net ecosystem exchange (NEE) based on carbon flux and productivity data.
• Analyzing relationships between soil moisture, temperature, and ecosystem productivity.
• Studying seasonal and interannual climate variability in alpine steppes based on air temperature and precipitation records.
• Calibrating or validating remote sensing products for carbon flux using ground-based eddy covariance measurements.

Strengths

• Data spans a three-year period from 2022 to 2024, providing a multi-year time series.
• Processed using internationally accepted standard methods for eddy covariance data.
• Underwent quality control with missing data supplemented by interpolation.
• Aggregated into daily values for ease of analysis.

Limitations

• A half-hourly data loss rate of 50% is reported, which may impact high-frequency analysis.
• 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.
