GPM SSMIS: Global Daily Precipitation Estimates from Microwave Sensors

Global gridded daily precipitation averages derived from satellite microwave sensors. Version 07 data from the NASA GES DISC provides estimates sensitive to liquid and ice-phase precipitation hydrometeors. The dataset is updated to March 2026.

Use Cases

• Analyze global precipitation patterns based on gridded daily averages.
• Study atmospheric water vapor and hydrometeors based on microwave sensor retrievals.
• Conduct climate trend analysis based on long-term satellite precipitation data.
• Validate precipitation models based on high-quality sensor-derived estimates.

Strengths

• Version 07 is the current and authoritative version, superseding older data.
• Data is based on retrievals from high-quality microwave sensors.
• Provides global coverage at a 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.
• Data may reflect temporal and sensor-specific bias inherent to satellite observations.
