C | The present version of this routine is a place-holder. | |
| 13 |
C | A production version needs to handle parameters from an | |

C zCoordInputData - These are used to select between different coordinate systems. |
| 62 |
C pCoordInputData The vertical coordinate system in the rest of the model is |
| 63 |
C rCoordInputData written in terms of r. In the model "data" file input data can |
| 64 |
C coordsSet be interms of z, p or r. |
| 65 |
C e.g. delZ or delP or delR for the vertical grid spacing. |
| 66 |
C The following rules apply: |
| 67 |
C All parameters must use the same vertical coordinate system. |
| 68 |
C e.g. delZ and viscAz is legal but |
| 69 |
C delZ and viscAr is an error. |
| 70 |
C Similarly specifyinh delZ and delP is an error. |
| 71 |
C zCoord..., pCoord..., rCoord... are used to flag when z, p or r are |
| 72 |
C used. coordsSet counts how many vertical coordinate systems have been |
| 73 |
C used to specify variables. coordsSet > 1 is an error. |
