| 16 | ! Purpose |
|---|
| 17 | ! ------- |
|---|
| 18 | ! Run the universal model radiative transfer once in a 1D column. |
|---|
| 19 | ! Useful for climate evolution studies etc. |
|---|
| 20 | ! |
|---|
| 21 | ! It can be compiled with a command like (e.g. for 25 layers): |
|---|
| 22 | ! "makegcm -p std -d 25 kcm1d" |
|---|
| 23 | ! It requires the files "callphys.def", "gases.def" |
|---|
| 24 | ! "traceur.def", and "run.def" with a line "INCLUDEDEF=callphys.def" |
