6.15. crop_params.nml

This file contains a single namelist called JULES_CROPPARM that sets time- and space-invariant parameters for each crop type.

6.15.1. JULES_CROPPARM namelist members

This namelist reads the values of parameters for each of the crop functional types. These parameters are a function of crop pft only. These parameters are only required if ncpft > 0. The crop pfts should be in the same order as in pft_params.nml.

JULES_CROPPARM::t_opt_io

Type:real(ncpft) Default:None

Optimum temperature (K).

JULES_CROPPARM::tmax_io

Type:real(ncpft) Default:None

Maximum temperature (K).
