Fortran: Module Interface areaMod (Source File: areaMod.F90)

   Area averaging routines
   Thes routines are used for area-average mapping of a field from one 
   grid to another.

USES:

   use shr_kind_mod, only: r8 => shr_kind_r8
   use clm_varcon, only : re
   use shr_const_mod, only : SHR_CONST_PI

PUBLIC TYPES:

   implicit none
   save
   integer, public, parameter :: maxovr = 100000

PUBLIC MEMBER FUNCTIONS:

   public :: areaini        ! area averaging initialization 
   public :: areaave        ! area averaging of field from input to output grids
   public :: areaini_point  ! area averaging initialization for single grid cell
   interface celledge
      module procedure celledge_regional  !Southern and western edges of grid cells - regional grid 
      module procedure celledge_global    !Southern and western edges of grid cells - global grid
   end interface
   interface cellarea
      module procedure cellarea_regional  !Area of grid cells (square kilometers) - regional grid
      module procedure cellarea_global    !Area of grid cells (square kilometers)- global grid 
   end interface
   public :: mkmxovr        ! find maxinum numver of overlapping cells between input/output grid
