GPM DPR: Global Monthly Precipitation Profiles at 0.25-Degree Resolution

Version 07 gridded precipitation data from the Global Precipitation Measurement (GPM) mission's Dual-frequency Precipitation Radar (DPR). The dataset provides monthly and daily summary statistics, including mean and standard deviation, at 0.25-degree and 5.0-degree spatial resolutions. It is produced by the National Aeronautics and Space Administration (NASA) and hosted by the GES DISC.

Use Cases

• Model validation and comparison based on gridded mean precipitation rates.
• Analyzing precipitation variability and distribution based on standard deviation statistics.
• Studying precipitation type and surface condition relationships based on conditioned variables.
• Long-term climate trend analysis based on monthly aggregated time spans.

Strengths

• Current Version 07 data, superseding all older versions.
• Provides data at two grid resolutions: 0.25-degree and 5.0-degree.
• Includes core statistics like measurement count, mean, and standard deviation for each grid box.
• Conditioned on surface type and precipitation type for many variables.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic or temporal bias inherent to the satellite's coverage.
