CropPhenology

INTERFACE:

 subroutine CropPhenology(num_pcropp, filter_pcropp)

DESCRIPTION:

Code from AgroIBIS to determine crop phenology and code from CN to handle CN fluxes during the phenological onset & offset periods.

USES:

   use clm_time_manager, only : get_curr_date, get_curr_calday, get_days_per_year
   use pftvarcon       , only : ncorn, nscereal, nwcereal, nsoybean, gddmin, hybgdd, &
                                lfemerg, grnfill, mxmat, minplanttemp, planttemp
   use clm_varcon      , only : spval, secspday

ARGUMENTS:

   integer, intent(in) :: num_pcropp       ! number of prog crop pfts in filter
   integer, intent(in) :: filter_pcropp(:) ! filter for prognostic crop pfts

CALLED FROM:

   subroutine CNPhenology
