interface_icosa_lmdz.f90 @ 2236

Last change on this file since 2236 was 2084, checked in by emillour, 6 years ago
Update the Dynamico-Venus interface to ensure that the initial local time for the physics is coherent. Add the possibility to reset local time (to midnight at longitude 0) using flag raz_date in def file (raz_date=1 to trigger reset of local time to midnight at longitude 0; default: raz_date=0 to do nothing).
