Is this computation a proper Helmholtz decomposition before computing divergence and vorticity?
Many Thanks.

Hi Claudia,
as far as I remember it is not a full Helmholtz decomposition. This has been found out by
Swarztrauber (NCAR) quite some time ago. However the difference is not big and the randomly
distributed error very small. IF you would like to do it in a proper way you can use
https://www2.cisl.ucar.edu/resources/legacy/spherepack
by Adams and Swarztrauber, which is a very comprehensive package.
For the ease of use you could try the python wrapper by Jeffrey Whitaker
https://pypi.org/project/pyspharm/
Of course the best option would be to provide a proper operator for cdo.
Cheerio,
Luis
