GPM SSMIS on F18: Global Daily Precipitation Grids

Version 07 global precipitation data from the GPM satellite's SSMIS instrument. The dataset provides daily averages on a 0.25-degree grid derived from microwave sensor retrievals. It is produced by NASA's GES DISC and supersedes older versions.

Use Cases

• Analyzing global precipitation trends for climate studies based on gridded monthly/daily averages.
• Studying atmospheric hydrometeor distribution based on microwave sensor retrievals sensitive to liquid and ice.
• Validating climate models using satellite-derived precipitation data.
• Monitoring regional precipitation variability over time based on daily gridded data.

Strengths

• Version 07 is the current and superseding version, indicating maintained data quality.
• Data is based on retrievals from high-quality microwave sensors.
• Provides global coverage on a 0.25-degree x 0.25-degree grid.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified as the last update date is in the future (2026-03-13).
