Requesting Ocean and Atmosphere variables from ERA5-hourly as netcdf leads to ocean variables incorrectly represented on atmospheric grid.

[sdat2]

I submitted a request for a regional box that roughly corresponds to the gulf of Mexico, for several variables of interest over the period of development of Katrina.

The surface atmosphere variables are correctly gridded.

The surface ocean variables only fill the top left quarter of the grid.

It looks like the lower resolution ocean variables have been added to the higher resolution atmospheric grid.
