Iowa Flood Study Rain Gauge Data For Satellite Validation

Four observation sites near Shueyville City, Iowa collected precipitation data during the Iowa Flood Studies field campaign from April 28 to May 20, 2013. Each site deployed three tipping bucket rain gauges recording 5-minute accumulations. The dataset was created by NASA's GPM Ground Validation program to evaluate satellite rainfall data for flood forecasting.

Use Cases

• Calibrating GPM satellite rainfall measurements using ground-based 5-minute precipitation accumulations.
• Evaluating the accuracy of satellite data for input into flood forecasting models.
• Analyzing spatial and temporal rainfall patterns across four specific gauge sites (15442, 15443, 15444, 22390) during a spring flood study.
• Comparing precipitation measurements from multiple co-located tipping bucket gauges at a single site for instrument reliability assessment.

Strengths

• Data provides high-temporal-resolution 5-minute precipitation accumulations from April 28 to May 20, 2013.
• Measurements were taken from four distinct sites, each with three co-located gauges for potential cross-validation.
• Dataset is part of a targeted NASA field campaign (IFloodS) designed specifically for satellite product validation.

Limitations

• Key technical details like row count, file size, and specific column names are unavailable across all sources.
• Sources conflict on the last updated date, listing either 2013-05-20 or a future date of 2026-03-13.
• Data coverage is limited to a 23-day period in spring 2013 and a specific region in Iowa.
