CNNDeposition

INTERFACE:

 subroutine CNNDeposition( lbc, ubc )

DESCRIPTION:

On the radiation time step, update the nitrogen deposition rate from atmospheric forcing. For now it is assumed that all the atmospheric N deposition goes to the soil mineral N pool. This could be updated later to divide the inputs between mineral N absorbed directly into the canopy and mineral N entering the soil pool.

USES:

    use clmtype
    use clm_atmlnd   , only : clm_a2l

ARGUMENTS:

    implicit none
    integer, intent(in) :: lbc, ubc        ! column bounds

CALLED FROM:

   subroutine CNEcosystemDyn, in module CNEcosystemDynMod.F90
