NASA S-Band Dual Polarimetric Radar Data from IPHEx Campaign

NPOL Doppler radar data was collected from April 27 to June 16, 2014, during the Integrated Precipitation and Hydrology Experiment field campaign in South Carolina. The dataset provides high-resolution measurements of precipitation in liquid, mixed, and ice phases using Plan Position Indicator, Range-Height Indicator, and PPI Sector scan modes. It is managed by the Global Hydrology Resource Center Distributed Active Archive Center.

Use Cases

• Validating Global Precipitation Measurement satellite retrievals using ground-based radar reflectivity and Doppler velocity measurements.
• Analyzing the three-dimensional structure of precipitation systems through Range-Height Indicator scans.
• Studying the microphysical properties of rain, snow, and mixed-phase precipitation using dual-polarimetric radar data.
• Investigating the relationship between precipitation patterns and hydrological response in a specific geographic region.

Strengths

• Data originates from a focused NASA field campaign (IPHEx) with a defined time range of April 27 to June 16, 2014.
• Provides measurements across multiple precipitation phases (liquid, mixed, ice) using high-resolution scan modes (PPI, RHI, PPS).
• Dataset is hosted on multiple authoritative platforms (NASA Earthdata, Data.gov), indicating its established use and importance.

Limitations

• Specific data volume, row count, and file size are not provided by any source.
• Sources conflict on the last updated date, reporting either 2014-06-16 or 2026-03-13.
• Column names and a complete data dictionary are unavailable from the provided descriptions.
