The values of $preff$ and $pa$ are read in the \textsf{start.nc} file, in the control array. 96 86 97 \item Interface pressures: 87 98 computed in \textsf{caldyn0.F, caldyn.F, integrd.F, leapfrog.F} -

r892 r927 52 52 The goal of this tool is to initialize the model the same way \textsf{gcm.F} does on 3D, but only on a single column, so that the physics may be tested without any dynamics. 53 53 54 It can be compiled with a command like (e.g. for 50 layers):54 It can be compiled (sequential only) with a command like (e.g. for 50 layers): 55 55 56 56 \textsf{makelmdz -p venus -d 50 rcm1d}
