GPM MHS on METOP-C (GPROF) Climate-based Radiometer Precipitation Profiling L3 1 day 0.25

Version 07 is the current climate-reference dataset from NASA's GPM mission, superseding all older versions. It provides daily global precipitation averages at a 0.25-degree grid resolution, derived from the METOP-C satellite's microwave humidity sounder (MHS). The data is processed using the GPROF algorithm with homogeneous ECMWF-Interim reanalysis as ancillary data to ensure consistency for long-term climate analysis.

Use Cases

• Analyzing long-term global precipitation patterns for climate studies based on the climate-reference data processing.
• Validating and calibrating climate models using homogeneous, gridded satellite precipitation data.
• Studying the sensitivity of microwave sensors to liquid and ice-phase precipitation hydrometeors in the atmosphere.
• Investigating atmospheric water vapor and its relation to precipitation events on a global scale.

Strengths

• Processed as a climate-reference product using homogeneous ECMWF-Interim reanalysis data for long-term consistency.
• Provides global daily precipitation averages at a 0.25-degree by 0.25-degree spatial resolution.
• Based on retrievals from high-quality microwave sensors sensitive to both liquid and ice-phase precipitation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total dataset size are unknown, which may limit suitability assessment.
• The ancillary ECMWF-Interim data has a 2-3 month lag behind regular production, which may affect near-real-time applications.
