callsedim_mod.F @ 2018

Last change on this file since 2018 was 1983, checked in by mvals, 7 years ago

Mars GCM:
Cosmetic/practical changes:

swmain and lwmain become modules swmain_mod, lwmain_mod
Addition of the intent in/out characteristics of variables in swmain_mod and lwmain_mod subroutines

Correction:

in callsedim_mod, declaration of variable tau(ngrid,nlay) corrected to tau(ngrid,naerkind)
