Last change on this file since 1243 was 1189, checked in by emillour, 11 years ago

Common dynamics: a couple of bug fixes:

  • Correctly account for the change in pressure, mass, etc. after modifying surface pressure following a call to the physics.
  • Corrected tracer advection, which is computed using values at the beginning of the time step, so it is done at Matsuno forward step.
