GPM MHS on METOP-A (GPROF) Radiometer Precipitation Profiling L3 1 month 0.25 degree x 0.2

Global gridded monthly precipitation averages derived from the GPM Microwave Humidity Sounder (MHS) on the METOP-A satellite. The data is processed using the GPROF algorithm with climate-reference ancillary data from ECMWF-Interim reanalysis to ensure homogeneity for long-term studies. Version 07 of this dataset is produced and hosted by NASA's GES DISC.

Use Cases

• Climate trend analysis based on homogeneous, climate-reference precipitation grids.
• Validation of climate models using global monthly precipitation averages from microwave sensors.
• Studying atmospheric water vapor and hydrometeor distribution as described in the platform tags.
• Investigating liquid and ice-phase precipitation sensitivity mentioned in the algorithm description.

Strengths

• Uses Version 07, the current and superseding version of the data set.
• Employs climate-reference ancillary data (ECMWF-Interim) for homogeneous time series.
• Based on retrievals from high-quality microwave sensors sensitive to precipitation hydrometeors.

Limitations

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