GPM GMI (GPROF): Global Daily Precipitation Grids at 0.25 Degree Resolution

Version 07 is the current version of this data set, superseding all older versions. The 3GPROF products provide global gridded daily precipitation averages derived from high-quality microwave satellite sensors, which are sensitive to liquid and ice-phase precipitation. This dataset is produced by the National Aeronautics and Space Administration (NASA) and was last updated on 2026-03-13.

Use Cases

• Conduct climate trend analysis based on global gridded precipitation averages.
• Validate and calibrate hydrological models using satellite-derived precipitation data.
• Study atmospheric water vapor and precipitation hydrometeors based on microwave sensor retrievals.

Strengths

• Data is at Version 07, indicating an ongoing, versioned processing pipeline.
• Provides global coverage at a 0.25 degree x 0.25 degree spatial resolution.
• Based on retrievals from high-quality microwave sensors sensitive to multiple precipitation phases.

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.
