This data is created using the script:
make_era5-rean_pod-data.py
The original data is from ERA5 reanalysis daily mean files of
zonal-mean zonal wind (ua), zonal-mean geopotential heights (zg), geopotential heights at 500 hPa, and surface air temperature (was).
The data was downloaded from hourly data (then compiled into daily means) from the Copernicus portal:
