KMHX NEXRAD Radar Reflectivity Images for IPHEx Campaign

160 stationary S-Band radars form the NEXRAD network, with this dataset containing browse images from the KMHX site. These PNG images of base reflectivity observations were collected from May 1, 2014 through June 12, 2014 to support the Global Precipitation Measurement mission's ground validation. The data was generated by NASA for the Integrated Precipitation and Hydrology Experiment in the southeastern United States.

Use Cases

• Validating satellite-based Quantitative Precipitation Estimation products using ground radar reflectivity images.
• Analyzing the spatial distribution and intensity of precipitation events in the southeastern U.S. during the IPHEx campaign.
• Studying the size distribution of water particles in the atmosphere via base reflectivity measurements.
• Supporting research on hydrologic forecasting by providing a ground-truth dataset for a specific time period.

Strengths

• Data originates from the established NEXRAD network of 160 S-Band radars, a standard for U.S. weather observation.
• Provides a focused temporal snapshot for a dedicated field campaign (IPHEx) from May 1 to June 12, 2014.
• Cross-platform presence on Data.gov and NASA EarthData indicates recognized importance and curation.

Limitations

• Dataset size, row count, and specific column names are not provided by any source.
• Sources conflict on the last updated date: Data.gov lists 2026-03 13, while NASA EarthData lists 2014-06-10.
• Data is limited to browse images in PNG format, not the underlying quantitative radar data files.
