Alan, I have not generated a global CS grid at ~40-km spacing.
I cc this answer to support list in case someone else has a ~40-km grid readily available.
If not your options are the following:

1. Generate a cube-sphere grid from scratch using scripts in

2. Adopt the new lat/lon/cap (LLC) grid for which grids are readily available at
4, 2, 1, 1/3, 1/6, 1/12, 1/24, and 1/48 degree grids.

I recommend you go with option 2 as this is where MITgcm/ECCO effort as a whole
is heading.  A description of the LLC grids and how to obtain them is here:
