One Year of ERA5 Wind Speed Data at 100m in Coastal China

Description This repository provides a one-year, high-resolution dataset of wind speed over coastal China based on ERA5 reanalysis data from the European Centre for Medium-Range Weather Forecasts (ECMWF). The data is extracted at 100 meters above ground level, representing conditions relevant for offshore and near-shore wind energy assessment, coastal meteorology, and atmospheric dynamics studies. The primary dataset is stored in NetCDF4 format and includes: u100: Zonal (east-west) wind component at 100 m v100: Meridional (north-south) wind component at 100 m Temporal coverage: 8784 hourly time steps (full calendar year, including leap day) Spatial resolution: 0.25° × 0.25° (~25 km), covering longitudes 100°E to 128°E and latitudes 16°N to 43°N Supplementary Data Two MATLAB .mat files are included to support spatial visualization and regional analysis: World.mat: Contains global coastline data useful for mapping wind vectors relative to geographic features. cities.mat: Provides names and GPS coordinates of key coastal cities in China for reference or targeted analysis.
