CMORPH IPHEx: Global Precipitation Analysis for Satellite Validation

GPM Ground Validation NOAA CPC Morphing Technique (CMORPH) IPHEx dataset consists of global precipitation analyses produced by the NOAA Climate Prediction Center. The data were collected during the Integrated Precipitation and Hydrology Experiment (IPHEx) field campaign to evaluate satellite precipitation accuracy and support hydrological modeling. It provides high-resolution global precipitation estimates derived from low orbiter satellite microwave observations.

Use Cases

• Validating satellite-based precipitation measurements against ground observations from the IPHEx campaign.
• Calibrating hydrological models for the North Carolina region using high-resolution precipitation inputs.
• Analyzing spatial and temporal patterns of global precipitation during the May-June 2014 period.
• Studying the application of the CPC morphing technique for blending satellite microwave observations.

Strengths

• Data is associated with a major, focused field campaign (IPHEx) designed for rigorous satellite validation.
• Provides global precipitation analyses at high temporal and spatial resolution, as described.
• Available in both raw binary and netCDF-4 formats, offering flexibility for different user workflows.

Limitations

• Metadata completeness is low; specific column names, row counts, and file sizes are not provided on any platform.
• Conflicting 'last updated' dates (2026-04-10 on Data.gov vs. 2014-06-14 on NASA Earthdata) create uncertainty about provenance and maintenance.
• Temporal coverage is limited to a specific 45-day period from May 1 to June 14, 2014.
