c
c   subject:
c   --------
c
c   Organisation of the physical parametrisations of the LMD 
c   martian atmospheric general circulation model.
c
c   The GCM can be run without or with tracer transport
c   depending on the value of Logical "tracer" in file  "callphys.def"
c   Tracers may be water vapor, ice OR chemical species OR dust particles
c
c   SEE comments in initracer.F about numbering of tracer species...
c
c   It includes:
c
c      1. Initialization:
c      1.1 First call initializations
c      1.2 Initialization for every call to physiq
c      1.2.5 Compute mean mass and cp, R and thermal conduction coeff.
c      2. Compute radiative transfer tendencies
c         (longwave and shortwave) for CO2 and aerosols.
c      3. Gravity wave and subgrid scale topography drag :
c      4. Vertical diffusion (turbulent mixing):
c      5. Convective adjustment
c      6. Condensation and sublimation of carbon dioxide.
c      7.  TRACERS :
c       7a. water and water ice
c       7b. call for photochemistry when tracers are chemical species
c       7c. other scheme for tracer (dust) transport (lifting, sedimentation)
c       7d. updates (CO2 pressure variations, surface budget)
c      8. Contribution to tendencies due to thermosphere
c      9. Surface and sub-surface temperature calculations
c     10. Write outputs :
c           - "startfi", "histfi" (if it's time)
c           - Saving statistics (if "callstats = .true.")
c           - Dumping eof (if "calleofdump = .true.")
c           - Output any needed variables in "diagfi" 
c     11. Diagnostic: mass conservation of tracers
