C | The present version of this routine is a place-holder. | |

C zCoordInputData - These are used to select between different coordinate systems. |
68 |
C pCoordInputData The vertical coordinate system in the rest of the model is |
69 |
C rCoordInputData written in terms of r. In the model "data" file input data can |
70 |
C coordsSet be interms of z, p or r. |
71 |
C e.g. delZ or delP or delR for the vertical grid spacing. |
72 |
C The following rules apply: |
73 |
C All parameters must use the same vertical coordinate system. |
74 |
C e.g. delZ and viscAz is legal but |
75 |
C delZ and viscAr is an error. |
76 |
C Similarly specifyinh delZ and delP is an error. |
77 |
C zCoord..., pCoord..., rCoord... are used to flag when z, p or r are |
78 |
C used. coordsSet counts how many vertical coordinate systems have been |
79 |
C used to specify variables. coordsSet > 1 is an error. |
