GSSTF_NCEP: Daily Global Surface Fluxes at 0.25 Degree Resolution

Daily satellite-based surface turbulent fluxes data covering the globe from 1990 onward, produced by Dr. Chung-Lin Shie under a NASA MEaSUREs project. The dataset is projected to an equidistant grid with a 0.25x0.25 degree cell size, resulting in global arrays of 1440x720 pixels. It integrates input from the SSM/I Version-6 product and the NCEP/DOE Reanalysis-2 product.

Use Cases

• Modeling ocean-atmosphere heat exchange based on surface turbulent flux data.
• Analyzing global wind stress patterns based on integrated satellite and reanalysis wind data.
• Studying evaporation and latent heat flux dynamics over oceans.
• Investigating trends in sea skin temperature and 2-meter air temperature from combined reanalysis sources.

Strengths

• Global spatial coverage at a 0.25x0.25 degree resolution, resulting in 1440x720 pixel arrays.
• Integrates multiple upgraded input datasets, including SSM/I V6 and NCEP/DOE Reanalysis-2.
• Produced under a NASA MEaSUREs project, indicating a research-grade source.

Limitations

• Data gap: Daily files are missing for October 21-22 and 26-28 in 1990.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
