Monthly Global Carbon Fluxes and Fire Emissions at 0.5-Degree Resolution

GEOS-Carb CASA-GFED V2 provides monthly average global estimates of Net Primary Production (NPP), heterotrophic respiration (Rh), and fire-related emissions. The dataset is derived from the CASA-GFED3 model and produced by NASA's Carbon Monitoring System through the GES DISC. Data generation concluded in December 2016.

Use Cases

• Modeling atmospheric CO2 concentrations by integrating monthly NPP and Rh flux estimates.
• Assessing the impact of wildfire emissions (FIRE) on regional carbon budgets over time.
• Estimating anthropogenic influence on carbon cycles by analyzing fuel wood burning emissions (FUEL).
• Validating satellite-derived carbon stock measurements using modeled heterotrophic respiration (Rh) data.
• Studying seasonal and interannual variability in Net Primary Production (NPP) across different biomes.

Strengths

• Global spatial coverage at a 0.5-degree x 0.5-degree resolution.
• Includes four key carbon cycle variables: NPP, Rh, FIRE, and FUEL.
• Data produced under NASA's Carbon Monitoring System for policy-relevant applications.

Limitations

• Temporal coverage is static, with the last update in 2016, limiting analysis of recent trends.
• Specific row counts, sample sizes, and validation metrics for the model outputs are not provided.
• Relies on model-derived estimates (CASA-GFED3) which contain inherent uncertainties not quantified here.
