optci_1pt_2.F @ 1525

Last change on this file since 1525 was 1461, checked in by emillour, 10 years ago
Titan GCM: Turned the common block "tgmdat.F" into a module "tgmdat_mod.F90". This fixes issues in "debug" mode with common variables which seemed to not be correctly shared between routines. EM
