Modeled Global Carbon Flux at 3-Hourly Resolution

CMS: Modeled Net Ecosystem Exchange at 3-hourly Time Steps, 2004-2010 provides global, gridded estimates of CO2 flux between land and the atmosphere. The dataset contains outputs from 15 global land surface models and four ensemble products from the MsTMIP project, covering a seven-year period. It is produced by the National Aeronautics and Space Administration.

Use Cases

• Validating and benchmarking terrestrial biosphere models against multi-model ensemble outputs.
• Analyzing spatial and temporal patterns of global carbon sources and sinks over a multi-year period.
• Studying the diurnal and seasonal variability of net ecosystem exchange at three different spatial resolutions.
• Investigating model uncertainty in carbon flux estimates by comparing results from 15 individual models.

Strengths

• Includes outputs from 15 distinct global land surface models, allowing for uncertainty analysis.
• Provides data at a high 3-hourly temporal resolution over a continuous seven-year time range (2004-2010).
• Offers global coverage at three spatial resolutions (0.5°, 2.0°x2.5°, 4.0°x5.0°) for flexibility in analysis.

Limitations

• Specific column names and the exact data structure are not documented in the provided sources.
• There is a conflict regarding the dataset's last update date: one source lists 2026-03-13, while another lists 2010-12 31.
