[MITgcm-devel] suggestion llc/cubed sphere

[Martin.Losch at awi.de]

Hi,

Jean-Michel is right, too. I found one experiment, where the angle information is included, but not in all, may be because my 
verification directory is not properly updated? Anyway. the angle information is NOT in the llc grids, and we need it not only 
for  tile009, but also for the tiles that contain the transition zone.

Hi Jean-Michel,

I think Martin et al are right, i.e. I double-checked the angle  
fields in e.g.
grid.t009.nc
are all 1. (=AngleCS)
and     0. (=AngleSN)

so no useful info.
Tile 9 above is the non-trivial polar cap tile
(in fact all other tiles are plain lat/lon),
so one would have expected that content to be different.

I suppose the angle info is missing in the grid generation part.

-p.
