Short summary
This study provides a high-resolution (0.25°, hourly) tropopause folding dataset for China (2014–2023) using ERA5 (ECMWF Reanalysis version 5) reanalysis data and a three-dimensional labeling method. It fills a critical data gap, enabling detailed spatiotemporal analysis of tropopause folding events. This validated resource provides a solid foundation for investigating stratosphere-troposphere transport and its impacts on near-surface air quality and extreme weather.
