GPM SSMIS F19: Global Monthly Precipitation Grids for Climate Studies

Version 07 climate-reference precipitation data uses homogeneous ECMWF-Interim reanalysis for consistent atmospheric conditions over time. 3GPROF products provide global gridded monthly precipitation averages derived from high-quality microwave sensors sensitive to liquid and ice-phase hydrometeors. This dataset is produced by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Climate trend analysis based on homogeneous, climate-referenced precipitation grids.
• Atmospheric water cycle modeling based on microwave-derived liquid and ice-phase precipitation data.
• Satellite data validation and intercomparison based on global gridded monthly averages.

Strengths

• Climate-Reference product designed for homogeneous time series analysis using consistent ECMWF-Interim ancillary data.
• Global coverage at a 0.25-degree x 0.25-degree spatial resolution.
• Data is from the current Version 07, superseding older versions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• ECMWF ancillary data has a 2-3 month lag behind regular production.
