GPM 3GPROFNOAA19MHS_CLIM: Global Monthly Precipitation Grids for Climate Studies

Version 07 is the current version of this climate-referenced precipitation dataset. The data provides global gridded monthly precipitation averages derived from the NOAA-19 satellite's Microwave Humidity Sounder (MHS) radiometer, processed using the GPROF algorithm with homogeneous ECMWF-Interim reanalysis ancillary data. It is produced by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Analyzing long-term global precipitation patterns for climate studies based on the climate-referenced 'CLIM' product design.
• Validating climate model outputs against satellite-derived precipitation averages based on gridded monthly data.
• Studiating atmospheric water vapor and hydrometeor distribution based on microwave sensor sensitivity described.
• Investigating regional precipitation anomalies over time using the 0.25-degree spatial resolution grid.

Strengths

• Uses Version 07, the current and superseding version of the data set.
• Designed as a Climate-Reference product using homogeneous ECMWF-Interim ancillary data for consistency over time.
• Provides global coverage at a 0.25-degree by 0.25-degree spatial resolution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The ECMWF-Interim ancillary data has a 2-3 month lag behind regular production, which may affect timeliness.
• Row count and exact temporal coverage are unknown, which may limit suitability assessment.
