Hello everyone

I'm seeking to perform sensitivity experiments where the surface roughness is changed on a aqua-planet simulation (idealise case) without triggering the wave model (LWCOU or LWCOU2W).
My first intuition was to look for Charnock parameter in the code. I modify RCHAR in surf/module/suvexc_mod.F90 and PDEFAULT in ifs/module/surface_fields_mix.F90 but without success.
Do you know where the surface roughness is initialise for an aqua-planet simulation and where to modify it?
Thanks again for your time and help.

Best regards,
Clément Bouvier

    Hello everyone,

    I found a solution. I tested viscosity in surf/module/suvexc_mod.F90 and Charnock in surf/module/vupdz0_mod.F90. I finally implement a solution in ifs/module/surface_fields_mix.F90 to be able to input the surface roughness for my sensitivity experiment.
    Thank you for your time!
