GPM_2AGPROFF14SSMI_CLIM: Climate-Referenced Satellite Precipitation Profiles

Global precipitation and atmospheric water vapor data from the SSM/I sensor on the DMSP F14 satellite, processed using the GPROF algorithm. The dataset is a climate-reference product using ECMWF-Interim reanalysis for homogeneous ancillary data to ensure consistency over time. Version 07 is the current version, produced by NASA's Goddard Space Flight Center.

Use Cases

• Climate trend analysis based on the climate-reference product design using homogeneous ancillary data.
• Precipitation profiling and uncertainty estimation based on the Bayesian retrieval algorithm described.
• Inter-sensor consistency studies based on the use of a common a-priori database across the GPM constellation.
• Atmospheric condition modeling based on the derived surface and atmospheric conditions required by the GPROF algorithm.

Strengths

• Provides a climate-consistent data record using ECMWF-Interim reanalysis as ancillary data.
• Employs a Bayesian algorithm that retrieves mean rain rate, vertical hydrometeor structure, and their uncertainty.
• Integrates data from multiple passive microwave sensors within the GPM constellation for broad coverage.

Limitations

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