Permafrost Thermal Response to Extreme Rainfall Across 131 Sites

131 permafrost sites across the Northern Hemisphere were analyzed to quantify soil temperature responses to extreme rainfall events. The dataset, created by Qian Li and published in 2026, integrates four extreme rainfall indices and uses three analytical approaches to identify distinct thermal response patterns. It reveals that rainfall generally cools shallow soils but warms deeper layers, with effects varying by regional climate and ecosystem characteristics.

Use Cases

• Analyze correlations between four extreme rainfall indices and soil temperature changes at different depths.
• Classify 131 permafrost sites into distinct soil thermal response patterns using principal component analysis.
• Model how regional factors like humidity, ground ice content, and soil organic matter regulate warming or cooling effects.
• Validate permafrost thaw projections by comparing extreme rainfall impacts against air temperature trends.

Strengths

• Data integrates observations from 131 distinct permafrost sites for broad spatial coverage.
• Analysis employs three distinct analytical approaches to quantify effects.
• Dataset explicitly links four extreme rainfall indices to soil thermal dynamics.

Limitations

• The dataset is small at 114.6 KB, indicating limited raw observational data or aggregated summary statistics.
• Specific column names and row counts for the underlying site data are not provided.
• Temporal coverage and resolution for the soil temperature and rainfall records are unspecified.
