Southern Appalachian Rain Gauge Data for GPM Validation

Rain gauge measurements were collected from 45 observation sites in the Southern Appalachian region as part of the Integrated Precipitation and Hydrology Experiment (IPHEx) field campaign. This dataset supports the Global Precipitation Measurement (GPM) mission by characterizing warm season precipitation in complex terrain. Data are provided by NASA in ASCII-csv format.

Use Cases

• Validating satellite-based precipitation estimates from the GPM mission using ground station measurements.
• Analyzing warm season precipitation patterns and regimes in mountainous regions.
• Studying hydrologic processes and water cycle dynamics in areas of complex terrain.
• Supporting the development and improvement of remote sensing precipitation algorithms.

Strengths

• Data originates from a focused NASA field campaign (IPHEx) with a clear scientific objective.
• Provides ground validation data from a network of 45 sites for satellite calibration.

Limitations

• Specific column names, row counts, and file sizes are not provided by any source.
• Sources conflict on the last updated date: one lists 2026-03-13, another lists 2014-12 31.
