CORDEX FPS: Downscaled Rainfall Projections for Southeastern Africa at 9-km Resolution

CORDEX FPS southeast Africa downscaled rainfall projections contain gridded annual precipitation parameters on a 5 arc-minute resolution (~9 km). The dataset includes ensemble mean and standard deviation, along with three quality diagnostics. Rasmus Benestad published the 604.1 MB dataset on figshare under a CC-BY-4.0 license, last updated in April 2026.

Use Cases

• Analyze projected changes in annual rainfall patterns based on the gridded downscaled ensemble mean.
• Assess model uncertainty for regional climate projections based on the provided ensemble standard deviation.
• Evaluate the quality of downscaling methods based on the three included diagnostics (normality, historical trends, interannual variability).
• Incorporate high-resolution precipitation data into hydrological or agricultural impact models based on the 9-km gridded parameters.

Strengths

• Data is provided at a high spatial resolution of approximately 9 kilometers (5 arc-minutes).
• Includes three specific quality diagnostics: normality of ensemble spread, historical trend matching, and description of interannual variability.
• Published under a permissive CC-BY-4.0 license, facilitating reuse.
• Last updated in April 2026, suggesting recent maintenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description does not specify the temporal coverage of the projections.
