Fellow CCM3-users,

Has anyone ever tested the sensitivity of CCM3 to the surface roughness ?

I am finding that the low level cloudiness decreases in the mid-latitudes in
spring and summer where the roughness length of the surface is increased.

Has this been noticed by anyone ? Does anyone have an idea of the processes
involved ?

Sincerely

Christine.
