GPM SSMI on F08 (GPROF) Climate-based Radiometer Precipitation Profiling L3 1 day 0.25 deg

Version 7 is the current version of this climate-referenced precipitation dataset from NASA. It provides global gridded daily precipitation averages derived from high-quality microwave sensors on the SSMI F08 satellite, processed using the GPROF algorithm with homogeneous ECMWF-Interim reanalysis data for climate consistency. The data is hosted by NASA's GES DISC and was last updated in March 2026.

Use Cases

• Conducting climate trend analysis based on homogeneous, climate-referenced precipitation retrievals.
• Validating and improving global climate models using satellite-derived daily precipitation averages.
• Studying the sensitivity of microwave sensors to liquid and ice-phase precipitation hydrometeors in the atmosphere.

Strengths

• Uses Version 7, the current and superseding version of the data.
• Provides climate-referenced homogeneity by using ECMWF-Interim reanalysis as ancillary data.
• Based on retrievals from high-quality microwave sensors sensitive to precipitation hydrometeors.

Limitations

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