GEOS-Carb CASA-GFED: 3-Hourly Global Carbon Fluxes at 0.5° x 0.625° Resolution

NASA's Carbon Monitoring System provides 3-hourly average net and gross ecosystem exchange (NEE/GEE) of carbon derived from the CASA-GFED3 model. The product offers global carbon source and sink data at a 0.5 degree by 0.625 degree spatial resolution to support policy and management activities. It is produced by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Modeling global carbon source and sink dynamics based on 3-hourly net ecosystem exchange (NEE) data.
• Analyzing spatial patterns of carbon fluxes based on the 0.5° x 0.625° gridded geospatial data.
• Integrating model-derived gross ecosystem exchange (GEE) with satellite observations for validation studies.
• Supporting near-term policy development with regional carbon flux information as mentioned in the description.

Strengths

• Data is produced by the authoritative National Aeronautics and Space Administration.
• Provides high-temporal-resolution 3-hourly averages for carbon flux analysis.
• Offers global coverage with finer-scale regional information as stated in the description.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and exact file sizes are unknown, which may limit suitability assessment.
• Data is model-derived (CASA-GFED3) and may contain biases inherent to the simulation.
