GPM SSMIS F17: Global Monthly Precipitation Averages at 0.25 Degree Resolution

Version 07 of the 3GPROF product provides global gridded monthly and daily precipitation averages derived from high-quality microwave sensors on the SSMIS F17 satellite. The data is produced by the National Aeronautics and Space Administration (NASA) and is hosted by the GES DISC. It is designed for climate studies, with sensors sensitive to both liquid and ice-phase precipitation hydrometeors in the atmosphere.

Use Cases

• Conducting climate trend analysis based on global gridded monthly precipitation averages
• Studying atmospheric water vapor and hydrometeor distribution based on microwave sensor retrievals
• Validating and calibrating climate models using satellite-derived precipitation data
• Investigating regional precipitation variability for climate impact assessments

Strengths

• Data is at Version 07, superseding all older versions for consistency
• Provides global coverage at a 0.25 degree x 0.25 degree spatial resolution
• Based on retrievals from high-quality microwave sensors sensitive to specific hydrometeors

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment for large-scale ML projects
