It sounds like you need a vector_wrap option that applies to the dataset. I think this should go on the RequestDataset with options like:

• wrap=True Wrap to -180 to 180.
• wrap=False Unwrap to 0 to 360.
• wrap=None (Default) Leave as is.

Have you tested with a "wrapped" grid?

Nice idea.
Was first thinking in a wrong way.

cdo is handling it like that (updated the notebook):
print lon[:]
[-78.75 -76.875 -75. -73.125 -71.25 -69.375 -67.5 -65.625 -63.75
-61.875 -60. -58.125 -56.25 -54.375 -52.5 -50.625 -48.75 -46.875
-45. -43.125 -41.25 -39.375 -37.5 -35.625 -33.75 -31.875 -30.
-28.125 -26.25 -24.375 -22.5 -20.625 -18.75 -16.875 -15. -13.125
-11.25 -9.375 -7.5 -5.625 -3.75 -1.875 0. 1.875 3.75
5.625 7.5 9.375 11.25 13.125 15. 16.875 18.75 20.625
22.5 ]

would it be possible to be consistent with that?

wrap option (True/False/None) could be a solution

Merci

Yeah, that should be possible. The data needs to be wrapped before the subset otherwise the masked values will be an issue.
