Tree Stem Methane Flux Models for Wetland and Upland Ecosystems

13,547 tree stem methane flux observations compiled from 90 published studies, supplemented by 2025 in-situ measurements. Random forest regression models were developed using five key predictors to estimate fluxes, showing a mean R2 of 0.65 for wetlands and 0.64 for uplands. The dataset was created by Pengfei Zhao and last updated in April 2026.

Use Cases

• Modeling tree stem methane fluxes based on structural traits like sampling height and diameter at breast height.
• Analyzing seasonal variability of methane emissions based on subsurface soil variables like temperature and moisture.
• Upscaling in-situ methane measurements to larger areas using gridded environmental predictors.
• Comparing methane flux dynamics between wetland and upland ecosystems based on model outputs.

Strengths

• Compiles 13,547 observations from 90 studies, providing a substantial basis for modeling.
• Models demonstrate predictive skill with mean R2 values of 0.65 for wetlands and 0.64 for uplands.
• Includes in-situ measurement data from two sites in 2025, adding recent observations.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
