FracWet

INTERFACE:

   subroutine FracWet(numf, filter)

DESCRIPTION:

Determine fraction of vegetated surfaces which are wet and fraction of elai which is dry. The variable ``fwet'' is the fraction of all vegetation surfaces which are wet including stem area which contribute to evaporation. The variable ``fdry'' is the fraction of elai which is dry because only leaves can transpire. Adjusted for stem area which does not transpire.

USES:

     use shr_kind_mod, only: r8 => shr_kind_r8
     use clmtype

ARGUMENTS:

     implicit none
     integer, intent(in) :: numf                  ! number of filter non-lake points
     integer, intent(in) :: filter(numf)          ! pft filter for non-lake points

CALLED FROM:

   subroutine Hydrology1 in module Hydrology1Mod
