GPM SSMIS on F18 (GPROF) Radiometer Precipitation Profiling L3 1 month 0.25 degree x 0.25

GPM_3GPROFF18SSMIS is a Level 3 precipitation product from NASA's Global Precipitation Measurement (GPM) mission. The dataset provides global gridded monthly and daily precipitation averages at a 0.25-degree resolution, derived from retrievals by the SSMIS sensor on the F18 satellite. Version 07 is the current and authoritative version, superseding all older releases.

Use Cases

• Conducting long-term climate trend analysis based on global gridded precipitation averages.
• Validating and calibrating climate models using satellite-derived precipitation data.
• Studying atmospheric hydrometeor distribution based on microwave sensor sensitivity to liquid and ice-phase precipitation.

Strengths

• Provides data at a 0.25-degree by 0.25-degree spatial grid, offering consistent global coverage.
• Based on retrievals from high-quality microwave sensors, which are sensitive to both liquid and ice-phase precipitation.
• Version 07 is the current authoritative version, indicating ongoing curation and updates.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total file size are unknown, which may limit suitability assessment for large-scale processing.
