GPM_3GPROFGCOMW1AMSR2_DAY: Global Daily Satellite Precipitation Grids at 0.25° Resolution

Version 07 is the current version of this global gridded precipitation dataset from NASA's GES DISC. The 3GPROF products provide daily and monthly precipitation averages derived from high-quality microwave sensors on the GCOM-W1 satellite, which are sensitive to liquid and ice-phase precipitation. The data is processed at a 0.25 degree by 0.25 degree spatial resolution.

Use Cases

• Modeling global precipitation climatology based on daily and monthly gridded averages.
• Analyzing atmospheric water vapor and hydrometeor distribution based on microwave sensor retrievals.
• Studying liquid and ice-phase precipitation sensitivity for climate model validation.
• Conducting long-term climate trend analysis based on global satellite-derived precipitation data.

Strengths

• Data is from Version 07, superseding all older versions for consistency.
• Derived from high-quality microwave sensors specifically sensitive to precipitation hydrometeors.
• 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.
• Row count is unknown, which may limit suitability assessment.
