Global Wetland Methane Emissions from LPJ-wsl Model, 2000-2021

2000-2021 estimates of global wetland methane emissions simulated by the LPJ-wsl model. The data includes two estimates based on different climate inputs: ground-based monthly observations from the Climatic Research Unit and daily reanalysis data from MERRA2. This dataset was created by Zhen Zhang and colleagues to support research on wetland methane feedback.

Use Cases

• Analyzing trends in wetland methane emissions over time based on the 22-year time series.
• Comparing model outputs based on different climate input datasets (CRU vs. MERRA2).
• Studying the spatial distribution of wetland methane sources based on the 0.5-degree grid cell data.
• Investigating the impact of climatic events like El Niño on methane emissions as referenced in the related studies.

Strengths

• Covers a 22-year time period from 2000 to 2021.
• Provides two distinct model estimates derived from different, well-established climate datasets (CRU and MERRA2).
• Includes a regional mask file for spatial analysis.
• Associated with peer-reviewed research published in journals like PNAS and Environmental Research Letters.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
