LPJ-EOSIM L2: Global Daily Simulated Wetland Methane Flux

LPJ-EOSIM Version 1 provides simulated daily wetland methane flux globally at a 0.5-degree spatial resolution. The model estimates emissions using simulated wetland extent, soil moisture, temperature, and carbon content, excluding small ponds, lakes, and coastal wetlands. Data are delivered in four Cloud Optimized GeoTIFF files per day, based on MERRA-2 and ERA5 forcing datasets, and include mean and standard deviation values.

Use Cases

• Studying natural greenhouse gas fluxes to support the U.S. Greenhouse Gas Center mission.
• Facilitating rapid detection and attribution of climate-carbon feedbacks based on simulated wetland characteristics.
• Informing strategic placement of measurement campaigns by identifying predicted biogeochemical hotspots.
• Analyzing global methane emission trends using daily, model-simulated flux data at 0.5-degree resolution.

Strengths

• Data is produced by a named, established model (Lund-Potsdam-Jena Earth Observation SIMulator).
• Provides global coverage at a consistent 0.5-degree spatial resolution.
• Includes both low-latency and high-latency collections to accommodate different CO2 concentration data availability.

Limitations

• Metadata completeness is low: column names, row counts, and exact file sizes are unknown across all platforms.
• The dataset is synthetic/model output, not direct observational measurements.
• High-latency data has a delivery lag of at least 5 months and up to 17 months.
