GPM DPR Ku-band Received Power: Calibrated Radar Data at 5 km Resolution

Version 07 is the current version of this calibrated received power data from the Ku-band Radar aboard the Global Precipitation Measurement (GPM) mission's core satellite. The data likely contains a swath of 245 km width with footprints about 5 km in diameter, collected by the National Aeronautics and Space Administration. The dataset was last updated on 2026-03-13.

Use Cases

• Modeling global precipitation patterns based on calibrated Ku-band radar power.
• Analyzing atmospheric water vapor and storm structure based on microwave radar returns.
• Validating and calibrating other satellite or ground-based precipitation measurements.
• Studying the spatial distribution of rainfall over a 245 km swath.

Strengths

• Data is from the current Version 07, superseding all older versions.
• Provides calibrated received power from a dedicated satellite instrument (GPM DPR).
• Offers a consistent scan pattern with a 245 km swath and approximately 5 km footprint resolution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total data volume are unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the satellite's orbit and mission lifetime.
