Parameters

cldf	layer cloud fraction
nlay	number of model vertical layers
ipseed	permute seed for random num generator
dz	layer thickness
de_lgth	layer cloud decorrelation length (km)
alpha	EXP/ER cloud overlap decorrelation parameter
lcloudy	sub-colum cloud profile flag array

mcica_subcol General Algorithm

• Call random_setseed() to advance randum number generator by ipseed values.

• Sub-column set up according to overlapping assumption:
  • For random overlap, pick a random value at every level
  • For max-random overlap, pick a random value at every level
  • For maximum overlap, pick same random numebr at every level

• Generate subcolumns for homogeneous clouds.
