Carbon Emissions and DOM Transport in Upper Yellow River Cascade Reservoirs

Spring thawing period data from Longyangxia, Lijiaxia, and Liujiaxia reservoirs and natural river sections in the upper Yellow River. The dataset contains surface and stratified water samples measuring greenhouse gas emission characteristics and dissolved organic matter (DOM) transport. It was authored by Li Chunhui and last updated on 2026-05-07.

Use Cases

• Modeling carbon dioxide (CO2) diffusion flux trends along river flow direction based on comparative reservoir data.
• Analyzing methane (CH4) emission patterns relative to CO2 in cascade reservoir systems.
• Investigating the vertical distribution of dissolved organic matter (DOM) and its correlation with reservoir depth.
• Assessing the relative influence of endogenous versus exogenous carbon sources on emissions in different reservoirs.

Strengths

• Data covers three distinct reservoirs (Longyangxia, Lijiaxia, Liujiaxia) and natural river sections for comparative analysis.
• Includes both surface and stratified water samples, allowing for depth-dependent analysis.
• Explicitly measures diffusion flux of CO2 (FCO2) and CH4 (FCH4) at the water-air interface.
• Released under a CC-BY-4.0 license, permitting broad reuse with attribution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is contained in a 6.0 MB ZIP file; internal structure and formats are unspecified.
