advtrac.F @ 3619

Last change on this file since 3619 was 1446, checked in by Ehouarn Millour, 14 years ago

Implemented modifications to enable running with only one tracer for planet types different from "earth". Rem: If flag 'planet_type' is set to "earth" (default behaviour) then there must be at least 2 tracers for the dynamics to function properly.

These updates do not induce any changes in model outputs with respect to previous revisions.
