7.3.3.9. ERA5 Mean Wave Direction Dataloader

ERA5 is a family of data products produced by the European Centre for Medium-Range Weather Forecasts (ECMWF). It is the fifth generation ECMWF atmospheric reanalysis of the global climate covering the period from January 1950 to present.

From their website:

ERA5 provides hourly estimates of a large number of atmospheric, land and oceanic climate variables. The data cover the Earth on a 30km grid and resolve the atmosphere using 137 levels from the surface up to a height of 80km. ERA5 includes information about uncertainties for all variables at reduced spatial and temporal resolutions.
