NASA IPHEX Micro Rain Radar Precipitation and Wind Data

April 22 to October 17, 2014 data from the Integrated Precipitation and Hydrology Experiment (IPHEx) in western North Carolina. The dataset contains vertically pointing Doppler radar measurements from four Micro Rain Radars (MRRs) capturing vertical velocity, drop size distribution, rainfall rate, and reflectivity. It was produced by the GHRC DAAC for ground validation of the Global Precipitation Measurement (GPM) mission.

Use Cases

• Validating satellite-based precipitation estimates from the GPM mission using ground-based radar reflectivity and rainfall rate measurements.
• Analyzing the vertical structure of storms through profiles of vertical velocity and drop size distribution.
• Studying the relationship between liquid water content and attenuation in precipitation systems.
• Investigating spatial and temporal rainfall variability during a focused field campaign in a mountainous region.

Strengths

• Provides continuous vertical profiles from four radar units during a major field campaign (IPHEx).
• Includes data from two radars for an extended period, covering from April through October 17, 2014.
• Cross-platform presence on NASA Earthdata and Data.gov indicates recognized importance for the research community.

Limitations

• Specific row counts, file sizes, and complete column lists are not provided by any source.
• Sources conflict on the last updated date, listing both 2014-10-17 and 2026-03-13.
• Data coverage is not continuous for all four instruments throughout the entire campaign period.
