NStateUpdate3

INTERFACE:

 subroutine NStateUpdate3(num_soilc, filter_soilc, num_soilp, filter_soilp)

DESCRIPTION:

On the radiation time step, update all the prognostic nitrogen state variables affected by gap-phase mortality fluxes. Also the Sminn leaching flux.

USES:

    use clmtype
    use clm_time_manager, only: get_step_size

ARGUMENTS:

    implicit none
    integer, intent(in) :: num_soilc       ! number of soil columns in filter
    integer, intent(in) :: filter_soilc(:) ! filter for soil columns
    integer, intent(in) :: num_soilp       ! number of soil pfts in filter
    integer, intent(in) :: filter_soilp(:) ! filter for soil pfts

CALLED FROM:

   subroutine CNEcosystemDyn
