Global Simulated Monthly Wetland Methane Flux at 0.5-Degree Resolution

LPJ-EOSIM L2 Global Simulated Monthly Wetland Methane Flux V001 provides model-estimated monthly methane emissions from global wetlands. The dataset is produced by the LPCLOUD organization using the Lund-Potsdam-Jena Earth Observation SIMulator, which incorporates factors like soil moisture, temperature, and carbon content. It offers global coverage at a 0.5-degree spatial resolution and is available in both low and high latency versions to support greenhouse gas research.

Use Cases

• Analyzing spatial patterns of wetland methane flux using the 0.5-degree resolution geospatial rasters.
• Studying climate-carbon feedback by utilizing the simulated flux data based on environmental drivers like soil moisture and temperature.
• Supporting the placement of measurement campaigns by identifying predicted biogeochemical hotspots from the model output.
• Comparing methane emissions derived from different meteorological forcing datasets (MERRA-2 and ERA5) provided in the collection.
• Assessing temporal variability in wetland methane emissions through the aggregated monthly time-series data.

Strengths

• Provides global coverage at a consistent 0.5-degree spatial resolution, enabling large-scale comparative studies.
• Model incorporates specific wetland characteristics and environmental drivers, including soil moisture, temperature, and carbon content.
• Offers both low and high latency data products to accommodate different research needs regarding data timeliness.
• Data is presented in Cloud Optimized GeoTIFF (COG) format, facilitating efficient cloud-based access and analysis.

Limitations

• Wetland definition excludes small ponds, lakes, and coastal wetlands, which may limit applicability to all aquatic methane sources.
• Key metadata such as row count, file size, and precise temporal coverage are unavailable across all platform descriptions.
• The license is ambiguously listed as 'other-license-specified' on some platforms and 'None' on others, creating uncertainty.
