GPM SSMIS on F17 (GPROF) Climate-based Radiometer Precipitation Profiling L3 1 month 0.25

Version 07 climate-reference precipitation data from the GPM mission's SSMIS sensor on the F17 satellite. The product provides global gridded monthly precipitation averages at 0.25-degree resolution, derived using the GPROF algorithm with homogeneous ECMWF-Interim reanalysis ancillary data for climate time series consistency. It is produced by the National Aeronautics and Space Administration (NASA) and hosted by the GES DISC.

Use Cases

• Analyzing long-term global precipitation patterns based on climate-referenced monthly grids
• Validating climate model precipitation outputs based on satellite microwave sensor retrievals
• Studiating atmospheric water vapor and hydrometeor distribution based on microwave radiometer sensitivity
• Conducting climate trend analysis based on homogeneous ancillary data from ECMWF-Interim reanalysis

Strengths

• Provides climate-homogeneous data using consistent ECMWF-Interim reanalysis ancillary data
• Based on retrievals from high-quality microwave sensors sensitive to liquid and ice-phase precipitation
• Global coverage at a 0.25-degree by 0.25-degree spatial resolution
• Current version is 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
• Ancillary data from ECMWF-Interim has a 2-3 month lag behind regular production
