Uganda Flood Inundation Model Ensemble Agreement Rasters

Six global flood models were intercompared to produce 90-meter resolution GeoTIFFs for Uganda. Each raster cell contains an integer value representing how many of the six models agree the location is wet. The data was produced by the IGAD Climate Prediction and Applications Center for a 100-year return period flood scenario.

Use Cases

• Validate and compare global flood model outputs based on the ensemble agreement metric.
• Map areas of high consensus for flood inundation in Uganda for a 100-year event.
• Assess flood exposure for infrastructure and population based on the 90-meter resolution raster data.
• Perform downstream risk analysis using the classified wet/dry cells from multiple models.

Strengths

• Data is derived from an intercomparison of six distinct global flood models.
• Rasters have a spatial resolution of approximately 90 meters (1/1200 decimal degrees).
• Published under a permissive CC-BY-4.0 license.
• Produced by a regional climate authority, the IGAD Climate Prediction and Applications Center.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
