Subroutines:
- allocate_npp_to_labile
- the biophysics and prescribed LAI.
- calc_ci_canopy
- ##### routines. (NK)
- canopy_rad
- Calculate PAR on sunlit and shaded foliage in layer Lc
- canopy_rad_setup
- solar zenith angle, and other canopy radiation parameters.
- canopy_transmittance
- canopyfluxes
- If PAR is not directly available, the following conversions may be used:
- gs_bound
- gs_from_ci
- optcurve
- Optimum curve, where OptCurveResult=x at 15 Celsius.
- photosynth_cond
- photosynth_sunshd
- qsat
- QSAT calculates saturation vapour mixing ratio
- qsimp
- resp_can_growth
- resp_can_maint
- resp_root
- Frootresp = fine root respiration (kgC/s/m2)
- respiration_autotrophic
- trapzd
- water_stress
- water_stress2
