! This subroutine is made to declare a new horizontale grid. |
| 11 |
|
|
! It has to have the same number of points as |
| 12 |
|
|
! the original Thus in this we routine we will only |
| 13 |
|
|
! add two variable (longitude and latitude). |
| 14 |
|
|
! Any variable in the file can thus point to this pair |
| 15 |
|
|
! through an attribute. This routine is very usefull |
| 16 |
|
|
