Precipitation Return Periods from ERA5, HADEX, and REGEN for Multiple Timeframes

Christopher Barnard provides return period calculations for total precipitation based on ERA5, REGEN, and HADEX datasets. The dataset includes 10-year, 20-year, and 50-year return periods for a selection of reference periods. It was last updated on 2026-04-13 and includes comparisons between reference periods to quantify event rarity and intensity.

Use Cases

• Modeling changes in extreme precipitation frequency based on return period comparisons.
• Assessing the rarity of historical precipitation events using calculated return periods.
• Comparing precipitation extremes across different reanalysis datasets (ERA5, HADEX, REGEN).
• Validating climate model outputs against return period data for various timeframes.

Strengths

• Includes return periods for three distinct timeframes (10, 20, and 50 years).
• Compares data from three established climate datasets (ERA5, REGEN, HADEX).
• Data volume is 2.0 GB, suggesting substantial detail.
• Released under a permissive CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Geographic scope is not specified in the provided metadata.
