Thank you! I tried to traceback to find the default drag coefficient values - it looks like cd_m is defined at some point before this, and roughness_mom is defined here in OM2. However the input_ice_gfdl.nml file doesn’t exist in the access-esm1.5 config files so I can’t find this code block at all.
&ocean_rough_nml
charnock = 0.032
do_cap40 = .false.
do_highwind = .false.
rough_scheme = 'beljaars'
roughness_heat = 5.8e-05
roughness_min = 1e-06
roughness_moist = 5.8e-05
roughness_mom = 5.8e-05
zcoh1 = 0.0
zcoq1 = 0.0
Are these roughness values prescribed anywhere in the esm configs? I struggle with searching in github across different branches as it doesn’t show lines of code that are in the repo in some branches so I feel like I’ve missed something.
