Short summary
We developed a three-dimensional wind dataset for the Yangtze River Delta with hourly information at one-kilometer resolution for the summers from 2021 to 2023. Using atmospheric modeling combined with ground observations and land surface data, the dataset represents local wind behavior more accurately than existing products. It supports studies of extreme weather, air pollution transport, wind energy planning, and low-altitude airspace safety in rapidly urbanizing regions.
