GPM Ground Validation Hydro-Estimator Rainfall Data for IPHEx

NASA's GPM Ground Validation Hydro-Estimator IPHEx dataset provides rainfall rate estimates derived from NOAA GOES satellite infrared data using the Hydro-Estimator algorithm. The data covers the North Carolina region for the IPHEx field campaign, offering 15-minute interval estimates from May 1, 2014, through June 16, 2014. These data are formatted as netCDF-4 files and were created in support of the Global Precipitation Measurement mission's ground validation efforts.

Use Cases

• Validating satellite-derived precipitation estimates against ground-based measurements for the IPHEx campaign.
• Analyzing the spatial and temporal patterns of rainfall rates in North Carolina during spring 2014.
• Studying the performance of the Hydro-Estimator algorithm for convective rainfall events.
• Providing high-temporal-resolution (15-minute) rainfall input for hydrological modeling in a specific region.

Strengths

• Data is derived from a well-defined algorithm (Hydro-Estimator) applied to operational NOAA GOES satellite imagery.
• Provides high temporal resolution rainfall estimates at 15-minute intervals.
• Dataset is focused on a specific, well-documented field campaign (IPHEx) for targeted validation.

Limitations

• Exact row count, file size, and specific column names are not provided by any source.
• Temporal coverage is limited to a six-week period in spring 2014.
• Spatial coverage is subset to only the North Carolina region, not the full continental U.S.
