Forcing inside the atmosphere

The concentration of greenhouse gases: CO2, CH4, N2O, CFC11, CFC12, should be set in file config.def.

Ozone

  • Run-time parameter in config.def: read_climoz = - 1, 0, 1 or 2
  • 0: analytic expression for the ozone field (see phylmd/ozonecm_m.F90)

  • - 1 (use with solarlong0 = 1000): ozone field made symmetric with respect to the equator, for use with annual mean insolation (used for aquaplanet runs)

  • 1: read day-night average of ozone field from a NetCDF file (this is what you want for CMIP 6 input).

  • 2: also read daylight average from the same file (good idea with Reprobus CMIP 5 input and if you run LMDZ with a few model layers in the mesosphere).
