IPHEx North Carolina Micro Rain Radar Precipitation Data

North Carolina precipitation data collected from May 1 to June 15, 2014, during the GPM Ground Validation Integrated Precipitation and Hydrology Experiment. The dataset contains measurements from a NASA ACHIEVE mobile laboratory's 24 GHz Micro Rain Radar, capturing detailed atmospheric profiles. It includes Doppler spectra, radar reflectivity, and derived hydrometeor properties for validating satellite observations.

Use Cases

• Validating Global Precipitation Measurement (GPM) satellite retrievals using ground-based radar reflectivity and Doppler velocity measurements.
• Analyzing rain microphysics through derived drop size distribution and liquid water content columns.
• Studying vertical atmospheric profiles for precipitation rate and path integrated attenuation during a specific field campaign.
• Calibrating radar algorithms using high-resolution spectral data from a vertically oriented K-band FM-CW radar.

Strengths

• Data originates from a NASA Goddard Space Flight Center (GSFC) ACHIEVE mobile laboratory, ensuring authoritative instrumentation.
• Captures a detailed 45-day observation period during the IPHEx field campaign in 2014.
• Provides multiple derived precipitation variables, including drop size distribution and rain rate, from raw Doppler spectra.

Limitations

• Key metadata conflicts exist: the 'last updated' date differs significantly between Data.gov (2026) and NASA Earthdata (2014).
• Specific row counts, file sizes, and the complete column schema are not provided by any source.
• Data is limited to a single geographic region (North Carolina) and a short, six-week temporal window.
