Duke Rain Gauge Precipitation Data from IPHEx Campaign

TB3 Model Tipping Bucket rain gauges collected precipitation data from May 1, 2014 through June 15, 2014 during the GPM Ground Validation IPHEx field campaign. The campaign was designed to characterize warm season orographic precipitation regimes in the Southern Appalachian region, including the Piedmont and Coastal Plain of North Carolina. Data is provided by the National Aeronautics and Space Administration in ASCII-csv format for each gauge location.

Use Cases

• Validating satellite-based precipitation estimates from the GPM mission using ground-based rain gauge measurements.
• Analyzing temporal precipitation patterns during the 2014 warm season in the Southern Appalachians.
• Studying the relationship between orographic features and precipitation regimes in regions of complex terrain.
• Supporting hydrological process studies by providing ground truth rainfall data for model input or calibration.

Strengths

• Data collection is focused on a specific, scientifically designed campaign (IPHEx) for ground validation.
• Provides a continuous 1.5-month time series of precipitation during the 2014 warm season.
• Collection targeted a region of complex terrain (Southern Appalachians) relevant for orographic precipitation studies.
• Cross-platform presence on Data.gov and NASA EarthData signals its importance for validation work.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• Sources conflict on license information, with some listing 'other-license-specified' and others 'None'.
• The most recent update date (2026-03 -13) on Data.gov is inconsistent with the data collection end date (2014-06-15), suggesting metadata maintenance rather than data update.
