GPM SSM/I Climate-based Radiometer Precipitation Profiles, 12 km Resolution

Version 7 climate-reference precipitation data from the GPM mission's SSM/I sensor on the DMSP F08 satellite. The Goddard Profiling (GPROF) algorithm uses a Bayesian method with an a-priori database to retrieve mean rain rates and vertical cloud structure. This product uses homogeneous ECMWF-Interim reanalysis ancillary data for climate consistency.

Use Cases

• Climate trend analysis based on homogeneous ancillary data from ECMWF-Interim reanalysis.
• Precipitation profile retrieval based on Bayesian algorithm using simulated brightness temperatures.
• Inter-sensor consistency studies based on the parametric GPM constellation approach.
• Uncertainty quantification of hydrometeor vertical structure based on the algorithm's weighted average solution.

Strengths

• Uses Version 7, the current algorithm version, superseding older data.
• Provides large spatial sampling as a strength mentioned in the description.
• Designed for climate consistency using homogeneous ECMWF-Interim ancillary data.

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.
