GPM Ground Validation KMRX NEXRAD Radar Reflectivity Images

GPM Ground Validation KMRX NEXRAD IPHEx V1 contains browse images of base reflectivity observations from the KMRX NEXRAD radar. These PNG images were collected during the Integrated Precipitation and Hydrology Experiment (IPHEx) field campaign from May 1 to June 12, 2014. The dataset supports ground validation for the Global Precipitation Measurement (GPM) mission and evaluation of Quantitative Precipitation Estimation products.

Use Cases

• Validating satellite-based Global Precipitation Measurement (GPM) data using ground-based radar reflectivity observations.
• Evaluating Quantitative Precipitation Estimation (QPE) products for improving hydrologic forecasting models.
• Analyzing the size distribution and amount of water particles in the atmosphere during the 2014 IPHEx campaign.
• Studying precipitation patterns and storm structure in the southeastern United States using S-Band radar imagery.

Strengths

• Data originates from the established NEXRAD network of 160 stationary S-Band radars.
• Provides a focused temporal sample from a specific field campaign (IPHEx) lasting over a month.
• Cross-platform presence on NASA Earthdata and Data.gov indicates recognized importance for the research community.

Limitations

• The dataset consists of browse images (PNG), not the original quantitative radar data files.
• Key metadata such as row count, file size, and exact column/feature names are not provided by any source.
• Sources conflict on the last updated date, reporting either 2014-06-12 or 2026-03 13.
