Simulations for autoconversion: F cases based on 195

 

F cases based on 195

This configuration use the autoconversion v9. We output the high frequency data to assess MJO.

Control configuration (f.195.001) includes:

  • new ozone, oxid and strataero
  • increase of sea-salt by 30%
  • prescribed_strataero_use_chemtrop = .true.
  • emissions that include  biomass burning emissions at the surface
  • zmconv_ke = 5.0E-6
  • micro_mg_berg_eff_factor = 1.
  • gamma_coef = 0.32
