wrong pole definition of `AUS` #7

Open larsbuntemeyer opened 11 months ago

larsbuntemeyer commented 11 months ago

The original definition of AUS seems to define the rotated grid using the south pole instead of the north pole as in all other CORDEX domain definitions. This is already corrected in the domain table. However, for CF aware tools like panoply or ncview, the wrong pole definition in ESGF NetCDF files leads to https://github.com/SciTools/cartopy/issues/2091 (of, e.g., coastlines).

All other domains seem to have a correct pole definition and can be plotted using cartopy.

I have been looking into this and for Australasia it seems to be a typo in the rotated pole. It plots correctly if I use 321.38; 60.31 and not if use the version on the CORDEX page 321.38; -60.31

I double checked this with the Met Office tool lampos

I also had some issues with S. America that I am working on too.

There are some complicated issues as well with the best way to plot the domains on a cartopy map as well with the simplest approach of setting the extent of the map giving misleading results. I hope to be able to fully document this soon.
