Mars GCM

  • implementation of a sub-grid water cloud fraction scheme (by A. Pottier): If CLFvarying is set to true in callphys.def, then the sub-grid cloud fraction routine is applied in watercloud.F and aeropacity.F.
  • accordingly modified files are: watercloud.F, aeropacity.F, callradite.F, conf_phys.F, phyetat0.F, phyredem.F90, physiq_mod.F, testphys1d.F, callkeys.h, newtsart.F, start2archive.F, lect_start_archive.F
  • added file: tcondwater.F90, used by watercloud.F to calculate the condensation temperature of water
  • watercloud.F, aeropacity.F, callradite.F are converted to module files as watercloud_mod.F, aeropacity_mod.F, callradite_mod.F
