Detailed Description

Subroutine that computes hydrometeors.

This routin computes the mixing ratios of cloud water, cloud ice, rain, and snow. The code is based on subroutines GSMDRIVE and GSMCOLUMN in the NMM model.

Parameters

[in]	P1D	Pressure (Pa).
[in]	T1D	Temperature (K).
[in]	Q1D	Specific humidity (kg/kg).
[in]	C1D	Total condensate (CWM, kg/kg).
[in]	FI1D	F_ice (fraction of condensate in form of ice).
[in]	FR1D	F_rain (fraction of liquid water in form of rain).
[in]	FS1D	F_RimeF ("Rime Factor", ratio of total ice growth to deposition growth).
[in]	CUREFL	Radar reflectivity contribution from convection (mm**6/m**3).
[out]	QW1	Cloud water mixing ratio (kg/kg).
[out]	QI1	Cloud ice mixing ratio (kg/kg).
[out]	QR1	Rain mixing ratio (kg/kg).
[out]	QS1	"Snow" (precipitation ice) mixing ratio (kg/kg).
[out]	DBZ1	Equivalent radar reflectivity factor in dBZ; i.e., 10*LOG10(Z).
[out]	DBZR	Equivalent radar reflectivity factor from rain in dBZ.
[out]	DBZI	Equivalent radar reflectivity factor from ice (all forms) in dBZ.
[out]	DBZC	Equivalent radar reflectivity factor from parameterized convection in dBZ.

CALMICT_old computes hydrometeors from the older version of the microphysics.

This routin computes the mixing ratios of cloud water, cloud ice, rain, and snow. The code is based on option MP_PHYSICS==95 in the WRF namelist and option MICRO='fer' in NMMB configure files.
