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

Two regional estimates of wetland methane emissions simulated by the LPJ-wsl model for 2000-2021, based on different climate forcing datasets. The dataset compares ground-based CRU observations with reanalysis-based MERRA2 data. Zhen Zhang from the University of Maryland, College Park created this data, which is referenced in peer-reviewed publications from 2017 and 2018.

Use Cases

• Comparing wetland methane emission estimates based on different climate forcing datasets (CRU vs. MERRA2).
• Analyzing trends in regional wetland methane emissions over a 22-year period (2000-2021).
• Validating or benchmarking other global methane emission models against LPJ-wsl simulations.
• Investigating the impact of climate variability, such as El Niño events, on wetland methane fluxes.

Strengths

• Data is derived from a peer-reviewed model (LPJ-wsl) referenced in PNAS and Environmental Research Letters.
• Provides two distinct estimates based on different climate datasets (CRU and MERRA2) for comparison.
• Covers a 22-year period (2000-2021), allowing for trend analysis.

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.
• Data may reflect the geographic or temporal biases inherent to the source climate forcing datasets.
