GPM SSM/I F13 Climate-based Radiometer Precipitation Profiles at 12 km

GPM_2AGPROFF13SSMI_CLIM is a Level 2 satellite dataset providing precipitation profiles from the SSM/I sensor on the DMSP F13 satellite. The data is processed using the GPROF algorithm with climate-consistent ECMWF-Interim reanalysis as ancillary data, aiming for homogeneous records over a climate time series. Version 07 is the current version, produced by NASA's Goddard Space Flight Center and distributed via the GES DISC.

Use Cases

• Analyzing long-term precipitation trends based on climate-referenced retrievals.
• Validating and calibrating atmospheric models based on Bayesian-derived rain rates and hydrometeor profiles.
• Studying global precipitation distribution and variability based on the large sampling provided by the satellite constellation.

Strengths

• Uses a consistent climate-referenced retrieval method with ECMWF-Interim reanalysis for homogeneous long-term records.
• Provides a large spatial and temporal sampling as part of the GPM constellation's 3-hour coverage.
• Algorithm retrieves a mean rain rate, vertical hydrometeor structure, and associated uncertainty.

Limitations

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