Examples of parameter file "data.exch2" can be found here; Some dimension files "SIZE.h" which match the "data.exch2" files are also provided.

naming convention: llc_120 : lat-lon-cap grid, 120-360-120 (=nRed,nGreen,nBlue) (grid-files in MITgcm_contrib/llc_120/grid_files )

SIZE.h.14t_120x120 :

llc_120 grid, 6-facets, tiles size = 120x120, no blank tiles
   (<=> largest tile size => minimum total Nb of tiles = 14)

SIZE.h.156t_20x60 : can be used with:

   llc_120, 6-facets, tiles =  20x60 + 12 blank tiles
or llc_120, 5-facets, tiles =  20x60 , no blank tiles
or cs-180,  6-facets, tiles =  20x60 +  6 blank tiles

data.exch2.llc_120_6f : llc_120, 6-facets, no blank tiles works for any tiling of facets and in particular with SIZE.h.14t_120x120

data.exch2.llc_120_6f.168t-12b : llc_120, 6-facets, 168 tiles - 12 blank tiles = 156 active tiles Notes: list and number of blank-tiles generaly depend on tiling of facets;

however, to blank out the last facet just requires listing all tiles
of the last facets and does not depend on precise tile-size but
just on Number of tiles.

works with SIZE.h.156t_20x60 (and also SIZE.h.156t_60x20 <- not provided)

data.exch2.llc_120_5f : llc_120, 5-facets (drop the last one), no blank tiles works for any facet tiling, and in particular with SIZE.h.156t_20x60

data.exch2.cs180.162t-6b_20x60 : regular CS-180 cube, 162 tiles - 6 blank (on face 2 along the Eq) = 156 active T. would work with SIZE.h.156t_20x60 (but what about grid-files ?)
