GPM GMI (GPROF): Global Gridded Monthly Precipitation Averages from Satellite Radiometers

Version 07 is the current and sole available version of this NASA precipitation dataset. 3GPROF products provide global gridded monthly and daily precipitation averages derived from high-quality microwave satellite sensors. These sensors are sensitive to both liquid and ice-phase precipitation hydrometeors in the atmosphere.

Use Cases

• Analyzing global precipitation climatology based on gridded monthly averages
• Studying atmospheric water vapor and hydrometeor distribution based on microwave sensor retrievals
• Validating climate model outputs against satellite-derived precipitation data
• Investigating regional precipitation trends for climate impact assessments

Strengths

• Data is from Version 07, the current and superseding version of the dataset
• Based on retrievals from high-quality microwave sensors sensitive to liquid and ice precipitation
• Produced by the National Aeronautics and Space Administration (NASA)
• Last metadata update recorded as 2026-03-13

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count and dataset size are unknown, which may limit suitability assessment
• Data may reflect geographic or temporal bias inherent to the satellite source and gridding method
