GPM Ground Validation Duke Microwave Radiometer IPHEx Atmospheric Data

May 1, 2014 through June 15, 2014 data from the Duke Microwave Radiometer collected during the Integrated Precipitation and Hydrology Experiment (IPHEx) field campaign in North Carolina. The dataset contains microwave radiance measurements at 23.8 and 31.4 GHz used to derive atmospheric water vapor and liquid water parameters. It was produced by NASA's Global Precipitation Measurement mission to study warm season precipitation in complex terrain.

Use Cases

• Validating satellite-based precipitation estimates from the GPM mission using ground-based microwave radiance measurements.
• Analyzing the relationship between atmospheric water vapor, wind speed, and precipitation formation in mountainous regions.
• Studying warm season orographic precipitation regimes and their impact on hydrologic processes in North Carolina.
• Deriving integrated water vapor and liquid water path from dual-frequency brightness temperature observations.

Strengths

• Provides a focused 1.5-month time series during the IPHEx field campaign for detailed process studies.
• Contains measurements at two specific microwave frequencies (23.8 and 31.4 GHz) sensitive to water vapor and liquid water.
• Serves as a key ground validation dataset for the NASA Global Precipitation Measurement mission.

Limitations

• The exact row count, file size, and complete column list are not specified on any platform.
• Data is limited to a specific 46-day period in 2014 and the geographic scope of the IPHEx experiment in North Carolina.
