ERA5-EX: Global Extreme Climate Indices and Compound Events

34 files contain 26 ETCCDI single indices and 8 compound event types derived from ERA5-Land daily reanalysis data. This dataset provides a 0.1-degree resolution global analysis of temperature and precipitation extremes from 1950 to 2025. It serves as a tool for quantifying changes in climate extremes over a 76-year period.

Use Cases

• Calculating trends in heatwave frequency and intensity based on ETCCDI temperature indices.
• Assessing concurrent drought and heat stress risks using the 8 defined compound event types.
• Validating climate models against high-resolution reanalysis data for extreme event attribution.
• Mapping the spatial distribution of precipitation extremes at a 0.1-degree global grid.

Strengths

• Includes a specific set of 34 calculated extreme climate indices and compound events.
• Covers a long temporal range from 1950 to 2025 (76 years).
• Provides high spatial resolution at 0.1 degrees, derived from the ERA5-Land reanalysis.
• Has a clear, permissive license (CC-BY-4.0) and is hosted on multiple platforms.

Limitations

• Column names and a precise row count are not provided in the available metadata.
• The dataset's large size (~5.7 GB) may present storage and processing challenges.
• Relies on model-based reanalysis data (ERA5-Land), which incorporates observational estimates.
