subroutine	CALLCL (P1D, T1D, Q1D, PLCL, ZLCL)

Detailed Description

Subroutine that computes LCL heights and pressure.

This routine computes the lifting condensation level pressure and height in each column at mass points. The height is above ground level. The equation used to find the LCL pressure is from Boltan (1980, MWR) and is the same as that used in subroutine CALCAPE.

This is a test version. Still to be resolved is the "best" parcel to lift.

Parameters

[in]	P1D	Array of parcel pressures (Pa).
[in]	T1D	Array of parcel temperatures (K).
[in]	Q1D	Array of parcel specific humidities (kg/kg).
[out]	PLCL	Parcel Pressure at LCL (Pa).
[out]	ZLCL	Parcel AGL height at LCL (m).
