! in this module interpolation is performed using integration of universal functions from z1 to z2,
! where z1 is measurement or lowest model level height and z2 is required height
! The input-output structure is preserved as much as possible as in the climate model (pbldia subroutine in pblflx)
!C* DIAGNOSIS OF WIND VELOCITY (AT HEIGHT Z = HWIND),
!C* OF POTENTIAL TEMPERATURE DEFICIT (BETWEEN HEIGHT Z = HTEMP AND SURFACE),
!C* OF SPECIFIC HUMIDITY DEFICIT (BETWEEN HEIGHT Z = HTEMP AND SURFACE)
!C* INPUT DATA USED:
!C* ARRAY AR2 (OUTPUT FROM DRAG3 - SUBROUTINE)
!C* AR2(1) - NON-DIMENSIONAL (NORMALIZED BY MONIN-OBUKHOV LENGTH)
!C* HEIGHT OF CONSTANT FLUX LAYER TOP
!C* AR2(8) - INTEGRAL TRANSFER COEFFICIENT FOR MOMENTUM
!C* AR2(9) - INTEGRAL TRANSFER COEFFICIENT FOR TEMPERATURE AND HUMIDITY
!C* ARRAY ARDIN
!C* ARDIN(1) - MODULE OF WIND VELOCITY AT THE TOP OF CONSTANT FLUX LAYER
!C* ARDIN(2) - POTENTIAL TEMPERATURE DEFICIT IN CONSTANT FLUX LAYER
!C* ARDIN(3) - SPECIFIC HUMIDITY DEFICIT IN CONSTANT FLUX LAYER
!C* ARDIN(4) - DIMENSIONAL HEIGHT OF CONSTANT FLUX LAYER TOP
!C* ARDIN(5) - = HWIND
!C* ARDIN(6) - = HTEMP
!C* OUTPUT DATA (ARRAY ARDOUT):
!C* ARDOUT(1) - MODULE OF WIND VELOCITY AT REQUIRED HEIGHT
Anna Shestakova
committed
!C* ARDOUT(2) - deficit of POTENTIAL TEMPERATURE between REQUIRED HEIGHT and the surface
!C* ARDOUT(3) - deficit of SPECIFIC HUMIDITY between REQUIRED HEIGHT and the surface
!C* UFWIND - UNIVERSAL FUNCTION FOR WIND VELOCITY
!C* UFTEMP - UNIVERSAL FUNCTION FOR SCALARS
