2026-06-16 A 1 km Hourly High-Resolution 3D Wind Field Dataset over the Yangtze River Delta during June-August 2021-2023 doi:10.57760/sciencedb.23752 en The 3D wind field dataset was generated through dynamic downscaling using the Weather Research and Forecasting (WRF) model, driven by ERA5 reanalysis data from the European Centre for Medium-Range Weather Forecasts (ECMWF). The simulation incorporates multi-source observational nudging, optimized physical parameterization schemes, and high-resolution land use updates to enhance the accuracy of local atmospheric processes. This dataset includes four variables: 10-meter zonal wind (U10m), 10-meter meridional wind (V10m), zonal wind profile (U), and meridional wind profile (V). The vertical wind profiles are provided on 32 ERA5-standard pressure levels from 1000 hPa to 10 hPa. All data are stored in NetCDF format with lossless compression enabled. Key variables are encoded using scale_factor and add_offset attributes, following the relation: real_value = scale_factor × packed_value + add_offset. The dataset complies with CF conventions and can be automatically decoded by standard tools such as xarray, NCL, and CDO, without manual intervention.
