|---|
| 23 | c PROGRAM useful to run physical part of the venusian GCM in a 1D column |
|---|
| 24 | c |
|---|
| 25 | c Can be compiled with a command like (e.g. for 50 layers) |
|---|
| 26 | c "makelmdz -p venus -d 50 rcm1d" |
|---|
| 27 | |
|---|
| 28 | c It requires the files "rcm1d.def" "physiq.def" |
|---|
| 29 | c and a file describing the sigma layers (e.g. "z2sig.def") |
