GPM_3PR_DES: Daily Satellite Precipitation Statistics at Surface and Fixed Heights

Version 07 is the current version of this data set, superseding older versions. It consists of descending daily statistics from the TRMM and GPM Precipitation Radar (PR) measurements. The data is provided by NASA and includes low (5x5 degree) and high (0.25x0.25 degree) resolution grids covering latitudes from 67S to 67N and 70S to 70N respectively.

Use Cases

• Analyzing mean and variability of rain rates based on daily satellite measurements
• Studying storm height and bright band height distributions using provided histograms
• Investigating path-integrated attenuation (PIA) and reflectivity statistics for atmospheric research
• Mapping precipitation fractions and correlation coefficients over global grids

Strengths

• Provides data at two spatial resolutions: a coarse 5x5 degree grid and a finer 0.25x0.25 degree grid
• Includes multiple statistical products: means, standard deviations, fractions, histograms, and correlation coefficients
• Version 07 is the current, superseding version, indicating maintained data quality

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Areas beyond ±40 degrees of latitude are padded with empty grid cells, reducing data coverage in polar regions
