Short Summary

This letter compares ERA5 and Global Flood Awareness System reanalyses with satellite observations to investigate high soil moisture events in Tropical Africa, highlighting the importance of satellites for monitoring such extremes.

Objective

• Investigate the accuracy of numerical models (ERA5 and Global Flood Awareness System) in estimating high soil moisture events in Tropical Africa compared to satellite observations.

Study Configuration

• Spatial Scale: Tropical Africa region
• Temporal Scale: Long-term (not specified)

Methodology and Data

• Models used: ERA5, Global Flood Awareness System reanalysis
• Data sources: Soil Moisture and Ocean Salinity satellite dataset, Aqua satellite dataset

Main Results

• Significant divergence between model outputs (ERA5 and Global Flood Awareness System) and both observations and reports.
• Good consistency between the two independent satellite datasets.

Contributions

• Highlights the essential role of satellites in monitoring soil moisture extremes, particularly in regions where models may not provide accurate estimates.
• Emphasizes the importance of combining multiple data sources for a more comprehensive understanding of water-related extremes.

Funding

• Not specified
