! This procedure tests the order of pressure values at half-levels |
| 12 |
! and full levels, and writes the vertical coordinates to files |
| 13 |
! "half_level.csv" and "full_level.csv" for a reference surface |
| 14 |
! pressure. We arbitrarily choose to test ngrid values of the |
| 15 |
! surface pressure, which sample possible values on Earth. |
