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
