ERA5 hourly pressure-level wind fields

ERA5 hourly pressure-level wind fields are Level 4 Copernicus Climate Data Store reanalysis data distributed by ECMWF and C3S ^[1]. The dataset provides hourly pressure-level data from 1940 to present and includes pressure-level u and v wind fields for global atmospheric-wind analysis, climate reanalysis, and historical numerical weather prediction context ^[1]. It is an assimilation and reanalysis product, not a direct satellite retrieval, so buyers should evaluate it as a gridded model-analysis wind field with documented licence and access terms rather than as sensor-native observations ^[1]. Access is open through the Copernicus Climate Data Store under a CC-BY licence ^[1].
