ncloud
This option specifies the cloud microphysics model. Options are
ncloud=0 – Original LDR cloud microphysics with prognostic liquid and ice condensates. Cloud cover is diagnosed.
ncloud=1 – Same as ncloud=0, but with updated autoconversion scheme
ncloud=2 – Same as ncloud=1, but with prognostic rain
ncloud=3 – Same as ncloud=2, but with prognostic snow and graupel
ncloud=4 – Same as ncloud=3, but with prognostic cloud cover and ncloud=0 autoconversion. This option is experimental.
