IPHEx Ground Validation Precipitation Data for Satellite Calibration

Hourly rainfall intensity data provides a 10-year reference for satellite precipitation validation. This dataset covers the core region of the Integrated Precipitation and Hydrology Experiment centered on the Pigeon River Basin in North Carolina. It was produced by the GPM Ground Validation team and hosted by the GHRC DAAC.

Use Cases

• Validating satellite-derived precipitation estimates from missions like GPM using ground-based reference data.
• Calibrating and evaluating regional hydrological models with high-resolution rainfall inputs.
• Analyzing long-term rainfall intensity patterns at an hourly scale over a specific basin.
• Supporting research on the relationship between precipitation measurement and hydrological response.

Strengths

• Provides a 10-year temporal record from December 31, 2007 to December 31, 2017.
• Offers high spatial resolution at 1 km2 for detailed regional analysis.
• Specifically designed for the critical task of satellite precipitation product validation.

Limitations

• Column names and exact row counts are not specified in the available metadata.
• Conflicting last updated dates exist between sources (2017-12-31 and 2026-03-13).
• Data is limited to the IPHEx core region, not a global or national coverage.
