Global monthly average data provides Net Primary Production (NPP), heterotrophic respiration (Rh), wildfire emissions (FIRE), and fuel wood burning emissions (FUEL) fluxes. The dataset is derived from the Carnegie-Ames-Stanford-Approach – Global Fire Emissions Database version 3 (CASA-GFED3) model. It was produced by the NASA Carbon Monitoring System and distributed by the GES DISC, with a last update in 2017.
Use Cases
- Modeling net ecosystem exchange (NEE) by combining NPP and Rh flux estimates.
- Analyzing spatial and temporal patterns of wildfire emissions (FIRE) and fuel wood burning (FUEL) to assess regional fire impacts on atmospheric carbon.
- Validating satellite-derived carbon stock products using modeled NPP and respiration fluxes.
- Investigating correlations between seasonal NPP cycles and heterotrophic respiration (Rh) across different biomes.
Strengths
- Provides four key carbon cycle variables (NPP, Rh, FIRE, FUEL) for integrated analysis.
- Offers global coverage at a consistent 0.5-degree spatial resolution.
Limitations
- Data is modeled output (CASA-GFED3), not direct observation, introducing uncertainty.
- Temporal coverage ends in 2017, limiting analysis of recent trends.
- Specific row counts, sample sizes, and validation metrics are not provided.
