GPM 3GPROF: Global Daily Satellite Precipitation Estimates at 0.25 Degree Resolution

GPM_3GPROFMETOPAMHS_DAY_CLIM is a Level 3 climate-reference dataset from NASA's GPM mission. It provides global daily mean precipitation estimates on a 0.25° x 0.25° grid, derived from microwave sensor retrievals using the GPROF algorithm with homogeneous ECMWF-Interim reanalysis data. Version 07 is the current version, superseding all older releases.

Use Cases

• Analyzing global precipitation climatology based on climate-referenced, homogeneous ancillary data.
• Studying atmospheric water vapor and precipitation hydrometeors based on microwave sensor sensitivity.
• Validating and calibrating climate models based on gridded daily precipitation averages.
• Investigating regional precipitation trends over time based on global 0.25-degree gridded data.

Strengths

• Provides climate-reference data using homogeneous ECMWF-Interim reanalysis ancillary data for consistent time-series analysis.
• Offers global coverage at a 0.25 degree x 0.25 degree spatial resolution.
• Based on retrievals from high-quality microwave sensors sensitive to liquid and ice-phase precipitation.

Limitations

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