Parameters

plyr	(IX,NLAY), model layer mean pressure in mb (100Pa)
ptop1	(IX,4), pressure limits of cloud domain interfaces (sfc,low,mid,high) in mb (100Pa)
cldtot	(IX,NLAY), total or stratiform cloud profile in fraction
cldcnv	(IX,NLAY), convective cloud (for diagnostic scheme only)
dz	(IX,NLAY), layer thickness (km)
de_lgth	(IX), clouds decorrelation length (km)
alpha	(IX,NLAY), alpha decorrelation parameter
IX	horizontal dimension
NLAY	vertical layer dimensions
iovr_rand	flag for random cloud overlap method
iovr_maxrand	flag for maximum-random cloud overlap method
iovr_max	flag for maximum cloud overlap method
iovr_dcorr	flag for decorrelation-length cloud overlap method
iovr_exp	flag for exponential cloud overlap method
iovr_exprand	flag for exponential-random cloud overlap method
clds	(IX,5), fraction of clouds for low, mid, hi, tot, bl
mtop	(IX,3),vertical indices for low, mid, hi cloud tops
mbot	(IX,3),vertical indices for low, mid, hi cloud bases

Detailed Algorithm

• Calculate total and BL cloud fractions (maximum-random cloud overlapping is operational).
• Calculte high, mid, low cloud fractions and vertical indices of cloud tops/bases.
