IPHEx Campaign Radar Reflectivity Images from KHTX NEXRAD

160 NEXRAD S-Band radar stations provide data for ground validation of the Global Precipitation Measurement mission. This dataset contains browse images of base reflectivity observations from the KHTX station during the Integrated Precipitation and Hydrology Experiment. Images cover a specific campaign period to evaluate Quantitative Precipitation Estimation products for hydrologic forecasting in the southeastern United States.

Use Cases

• Validating Global Precipitation Measurement satellite rainfall estimates using ground-based radar reflectivity data.
• Analyzing the spatial distribution and intensity of precipitation events in the southeastern U.S. during May-June 2014.
• Evaluating Quantitative Precipitation Estimation algorithms for improved hydrologic forecasting models.
• Studying the size distribution and amount of water particles in the atmosphere via base reflectivity measurements.

Strengths

• Data originates from the established NEXRAD network of 160 S-Band weather radars, a standard reference system.
• Temporal coverage is precisely defined for the IPHEx field campaign from May 1 to June 16, 2014.
• Cross-platform presence on NASA Earthdata and Data.gov indicates recognized importance and curation.

Limitations

• Core data dimensions (row count, file size) and specific column names are not provided by any source.
• Sources conflict on license (other-license-specified vs. None) and last updated date (2026-03 vs. 2014-06).
• Dataset consists of browse images (PNG format), which may limit quantitative analysis compared to raw radar data.
