| 11 | ! Purpose |
|---|
| 12 | ! ------- |
|---|
| 13 | ! Run the physics package of the universal model in a 1D column. |
|---|
| 14 | ! |
|---|
| 15 | ! It can be compiled with a command like (e.g. for 25 layers): |
|---|
| 16 | ! "makegcm -p std -d 25 rcm1d" |
|---|
| 17 | ! It requires the files "callphys.def", "z2sig.def", |
|---|
| 18 | ! "traceur.def", and "run.def" with a line "INCLUDEDEF=callphys.def" |
