[MITgcm-support] Grid Generation

[ESTANISLAO GAVILAN PASCUAL-AHU]

Dear Zhan Lian,
  I am not sure that MITgcm can do that (I hope someone can correct me otherwise). "SPGrid" generates curvilinear grids with a constant grid size. There are some alternative such as NEMO (really similar to mitgcm) where you can define a part of the domain with a subgrid (i.e. a smaller than the rest). I think it is inside the AGRIF module.

Kind regards,

Estanislao

> I'm facing a problem of geographically variable grid generation. I'm trying to study the long-term variation of mesoscale eddies in the Southern Indian Ocean. The horizontal resolution should be high (~1/20 degree) in this area. However, since the Southern Indian Ocean is easy to be effected by the Indonesia Through Flow and ACC. I would like to make a quasi-global model.  To save the consumption of simulation, except for the Southern Indian Ocean, the resolution can be coarse (~1 degree).

I have noticed that in the latest manual, there is a brief introducion about a grid generation suite named "SPGrid". Somehow, I didnot find how to get this software and I am not sure if it can meet my requirment. Any suggestions would be appreciated.
