GPM TRMM Climate-based Radiometer Precipitation Profiles: Monthly 0.25° Grid

Version 07 is the current and only available version of this climate-referenced precipitation dataset, superseding all older releases. The product provides global gridded monthly precipitation averages derived from high-quality microwave sensors sensitive to liquid and ice-phase hydrometeors. It is produced by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Conducting climate trend analysis based on the climate-referenced, homogeneous ancillary data used in the retrieval algorithm.
• Studying global precipitation distribution based on the 0.25-degree gridded monthly averages.
• Validating atmospheric models using precipitation profiles derived from microwave sensor retrievals.
• Analyzing the sensitivity of precipitation to surface and atmospheric conditions based on the GPROF algorithm methodology.

Strengths

• Data is specifically designed for climate studies, using homogeneous ancillary data from ECMWF-Interim reanalysis to ensure consistency over the time series.
• Provides global coverage at a 0.25-degree spatial resolution.
• Version 07 is the definitive current version, with older versions superseded and unavailable.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total dataset size are unknown, which may limit suitability assessment.
• The ancillary data used has a 2-3 month lag behind regular production, which may affect timeliness for some applications.
