Apply different cloud fraction parameterizations in a vertical column

Hi!

I am interested to have different cloud fraction parameterizations in the Wrf model. One that is applied in the lowest part, about 200 m (namelist, icloud=1, threshold for cloud water and cloud ice), and another that is applied above 200 m (namelist, icloud=2, Xu and Randall-parameterization).

Is this possible without too much change of the Fortran code? The calculations of cloud fraction are made in the radiation part of the model. We are using ra_lw_physics=4 and ra_sw_physics=4.

Thankful for help!

Best,
Martin Hagman
