inifis.F @ 517

Last change on this file since 517 was 485, checked in by aslmd, 13 years ago
LMDZ.MARS: added keyword tituscap. MESOSCALE: corrected a nasty bug in initializing surface deposits (no effect thus far because is set to 0 in surfini). also corrected mars=12 for ccn tracers NOT to be passed through boundaries. UTIL/PYTHON minor fix for redope.
