GPM DPR: Daily Gridded Satellite Precipitation Profiles at 0.25-Degree Resolution

Version 07 is the current version of this NASA precipitation dataset. The Level 3 DPR algorithm accumulates instantaneous precipitation estimates from the Global Precipitation Measurement mission's Dual-frequency Precipitation Radar into daily and monthly gridded products. These products provide summary statistics, including the number of measurements, mean, and mean square, for 0.25-degree by 0.25-degree grid boxes, conditioned on surface and precipitation type.

Use Cases

• Modeling global precipitation climatology based on daily gridded mean rain rates.
• Validating ground-based radar or other satellite data using the gridded standard deviation and measurement count statistics.
• Analyzing precipitation type and surface condition interactions using the conditioned data fields mentioned in the description.
• Comparing long-term precipitation trends using the monthly aggregated product referenced in the description.

Strengths

• Data is from NASA's authoritative Global Precipitation Measurement (GPM) mission.
• Provides daily and monthly aggregated products for temporal analysis.
• Offers data at two spatial resolutions, 5.0 degrees and 25 km, as mentioned in the description.
• Includes core statistics like mean, standard deviation, and measurement count per grid box.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description notes means are conditioned on precipitation being present, which may exclude zero-rainfall data.
