Mars GCM:
Implementation of the IRabs-to-VISext dust scenario conversion, depending on the GCM effective radius :

  • new flag 'reff_driven_IRtoVIS_scenario', false by default, must be set to true to use this dynamic conversion (otherwise, the coefficient takes the constant value of 2.6, eqv to reff=1.5um, as before) A specific line is added in deftank/callphys.def.GCM6
  • this flag requires the 'dustiropacity' to be set to 'tes' to match the IR scenario's wavelength. 'mcs'-like dso diagnostics can only be produced by the use of the post-processing tool util/aeroptical.F90
  • the variable IRtoVIScoef is computed in aeropacity via the GCM CDOD ratio : tau_pref_gcm_VIS/tau_pref_gcm_IR (only at the first call to callradite during each physical timestep)
  • change read_dust_scenario into module read_dust_scenario_mod

    24662466microphysics (just like water clouds). The amplitude is spantCO2, also read from callphys.def
    24672467- The previous logical microphysco2 has been removed.
    2468 - Cloud opacity at 1µm is now computed in the co2cloud.F routine

    24692469- Most of the co2 ice clouds scheme writediagfi are now in co2clouds.F
    24702470- Some cleaning of the CO2 ice clouds routine has been done. Not perfect yet!
     
    24822482  if a gravity wave propagates to the mesosphere or not (wheter the wave saturates on its way or not).
    24832483  The sub-grid temperature distribution is cancelled if the saturation index value of the column (between 12 and 80 km) is > 0.1, and is applied (+/- 3K) otherwise. if the keyword satindexco2=.true. in callphys.def (only applies if CLFvaryingCO2=.true. anyway). If set to .false., deactivate this filter and the sub grid T distribution applies everywhere and everytime. See comments in co2clouds.F
    2484 - All that you need to launch a GCM run with co2 clouds is described in co2clouds.F comments. Ehouarn Millour and Anni Määttänen have the files.
