CBalanceCheck

INTERFACE:

 subroutine CBalanceCheck(lbc, ubc, num_soilc, filter_soilc)

DESCRIPTION:

On the radiation time step, perform carbon mass conservation check for column and pft

USES:

    use clmtype
    use clm_time_manager, only: get_step_size

ARGUMENTS:

    implicit none
    integer, intent(in) :: lbc, ubc        ! column bounds
    integer, intent(in) :: num_soilc       ! number of soil columns in filter
    integer, intent(in) :: filter_soilc(ubc-lbc+1) ! filter for soil columns

CALLED FROM:

   subroutine clm_driver1
