GPM DPR: Daily Global Precipitation Profiles from Satellite Radar

GPM DPR Precipitation Profile 1 Day Ascending 0.25 degree x 0.25 degree V07 is a NASA dataset providing daily, gridded precipitation estimates from the Dual-frequency Precipitation Radar (DPR) on the Global Precipitation Measurement (GPM) satellite. The Level 3 algorithm accumulates instantaneous precipitation retrievals into 0.25-degree grids, providing core statistics like measurement count, mean, and mean square for each grid box. Version 07 is the current and authoritative version, superseding all older releases.

Use Cases

• Modeling global precipitation patterns based on daily gridded mean rain rates.
• Comparing satellite-derived precipitation with other data sources based on the gridded, standardized format.
• Analyzing precipitation statistics conditioned on surface or precipitation type as described in the algorithm.
• Studiating the vertical structure of precipitation using the three-dimensional height fields mentioned.

Strengths

• Provides a current, authoritative version (V07) that supersedes all older data.
• Offers data in a convenient, gridded form at two resolutions (5.0 degrees and 25 km) for easier analysis.
• Includes core statistics per grid box, such as the number of measurements, mean, and mean square for the daily product.

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.
