78    Some grid information - see MITgcm/model/inc/GRID.h for details:
79    xC  :: longitude East of center of grid cell
80    yC  ::latitude North of center of grid cell
81    xG  :: longitude East of SouthWest corner
82    yG  :: latitude North of SouthWest corner
83    dxG :: distance in m between SouthWest and SouthEast corner
84    dyG :: distance in m between SouthWest and NorthEast corner
85    
86    aCS :: cosine(alpha) relative to geographic direction at grid cell center
87    aSN :: sine(alpha) relative to geographic direction at grid cell center
88    
89           alpha = angle of model uVel direction vs geographical East
90                 = angle of model vVel direction vs geographical North
