Data and Reproducibility Materials for "Pan-Arctic Rapid Sea-Ice Loss: Spatially Dispersed Components and Definition-Dependent Cross-Scale Event Correspondence"

This dataset contains study-specific processed data and reproducibility materials supporting the manuscript “Pan-Arctic Rapid Sea-Ice Loss: Spatially Dispersed Components and Definition-Dependent Cross-Scale Event Correspondence.” The archive includes pan-Arctic and local-event catalogs, spatial-component and sensitivity results, cross-scale correspondence and matched-analysis outputs, regional diagnostic results, and the ERA5-derived cyclone-track dataset used in the study. Upstream NSIDC and ERA5 source data are not redistributed; their original sources and versions are documented in the accompanying README and manuscript.
