NEXRAD Radar Reflectivity Images for IPHEx Campaign

KCAE NEXRAD radar data from May 1 to June 12, 2014, provides browse images of base reflectivity in PNG format. These images were collected during the Integrated Precipitation and Hydrology Experiment (IPHEx) to support ground validation for the Global Precipitation Measurement (GPM) mission. The dataset is managed by the GHRC DAAC and is part of a broader effort to evaluate precipitation estimation products for hydrologic forecasting in the southeastern United States.

Use Cases

• Validating satellite-based precipitation estimates from the GPM mission using ground-based radar reflectivity observations.
• Analyzing the spatial distribution and intensity of rainfall events in the southeastern U.S. during the IPHEx field campaign.
• Developing and testing hydrologic forecasting models by providing detailed precipitation input data.
• Studying the size distribution of water particles in the atmosphere through base reflectivity measurements.

Strengths

• Provides data from a specific, well-documented field campaign (IPHEx) with a precise time range of May 1 to June 12, 2014.
• Sourced from the established NEXRAD network of 160 S-Band radars, a standard for U.S. weather observation.
• Cross-platform presence on NASA Earthdata and Data.gov signals its importance and curation for scientific use.

Limitations

• The dataset consists of browse images (PNG), not the primary quantitative radar data, limiting detailed analysis.
• Column names and exact row or file counts are unknown across all sources.
• Conflicting license information: one source specifies 'other-license-specified' while another lists 'None'.
