GPM GPROF: Global Daily Precipitation Grids from NOAA-20 Satellite

GPM_3GPROFNOAA20ATMS_DAY_CLIM is a Version 07 climate-reference dataset from NASA's GES DISC. It provides global daily precipitation averages at a 0.25-degree grid resolution, derived from NOAA-20 ATMS microwave radiometer retrievals. The data uses homogeneous ECMWF-Interim reanalysis as ancillary input for climate time series consistency.

Use Cases

• Climate trend analysis based on homogeneous, climate-referenced precipitation grids.
• Validation of atmospheric models based on microwave sensor-derived liquid and ice-phase hydrometeor data.
• Studying global precipitation distribution based on daily 0.25-degree gridded averages.

Strengths

• Uses Version 07, the current and superseding version of the data set.
• Provides climate-consistent data using homogeneous ECMWF-Interim reanalysis ancillary data.
• 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 is unknown, which may limit suitability assessment.
