Global Flood Maps from IFloodS Campaign

Flood estimates provide global coverage at a 0.25-degree spatial resolution every 3 hours. The dataset was created by NASA to support the Iowa Flood Studies (IFloodS) experiment, which combined ground instruments, advanced radars, and satellite overpasses. Data collection occurred from March 26, 2013, through June 30, 2013.

Use Cases

• Validating satellite precipitation estimates using ground-based radar and instrument data from the IFloodS campaign.
• Analyzing the spatial and temporal evolution of flood events at a 3-hourly, global scale.
• Comparing flood map outputs in KMZ, JPG, or GIF formats for visualization and communication.
• Studying the relationship between precipitation amount/rate and resulting flood inundation.

Strengths

• Data integrates multiple sources, including satellite overpasses, ground instruments, and advanced weather radars.
• Provides high temporal resolution with global flood estimates generated every 3 hours.
• Covers a focused 3-month campaign period designed for detailed validation studies.

Limitations

• Exact row count, file size, and specific column names are not provided by any source.
• Sources conflict on the last updated date: one platform lists 2026-03-13, while another lists the end of the data period, 2013-06 30.
• License is ambiguously listed as 'other-license-specified' without clear terms.
