MiCASA: 3-Hourly Net Ecosystem Exchange Fluxes at 0.1 Degree Resolution

MiCASA is a revised biogeochemical model estimating Net Ecosystem Exchange (NEE) fluxes globally. The model, developed by NASA, uses satellite-derived inputs like MODIS land cover and burned area data to calculate Net Primary Production (NPP) based on light use efficiency. The dataset provides 3-hourly flux estimates at a 0.1-degree spatial resolution.

Use Cases

• Modeling global carbon budgets based on satellite-derived fPAR and environmental scalars.
• Analyzing the impact of fire emissions on carbon fluxes based on burned area data.
• Studying vegetation productivity dynamics based on temperature and moisture limitation scalars.
• Comparing carbon flux estimates from different model versions (CASA-GFED3, GFED5).

Strengths

• Model incorporates multiple satellite-derived inputs, including MODIS land cover (MCD12Q1) and burned area (MCD64A1).
• Provides high temporal resolution (3-hourly) and spatial resolution (0.1-degree) estimates.
• Based on a long-standing model lineage (CASA-GFED3) with documented development history.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
