The problems of the dimension of variables in CESM

[luomin_953@126_com]

The dimensions of variables of u, v and q (refers to state%u, state%v and state%q in CESM) are two, like this pattern of var (:ncol,:pver). The first dimension of ncol indicates the number of grids. It means the two-dimensional spatial information was transformed to one dimension in source code of CESM. The question is that how to determine the south-north, and west-east directions in the calculation of wind divergence and wind gradient.

Thanks for any helps
Yours

Hello!

A couple places to look that should help you:

1. $CAM/src/dynamics/<DYCORE>/dyn_grid.F90
subroutine: get_dyn_grid_info
2. $CAM/src/infrastructure/phys_grid.F90
subroutine: phys_grid_init()

Let me know if that doesn't help.
