[MITgcm-support] cubed sphere question - higher resolution grid files?

[Dimitris Menemenlis]

Hi Flynn, in case cs96 is not sufficient, a set of routines that can generate cubed-sphere topologies is available here:
https://wwwcvs.mitgcm.org/viewvc/MITgcm/MITgcm_contrib/high_res_cube/matlab-grid-generator/

There may be newer versions available somewhere but this is the code that Chris Hill and I used to generate the cs510 grid,
"It Was Twenty Years Ago Today"!

Cheers, D.
