fluxes

Fluxes calculated by the model (turbulent heat exchange, radiation, CO2)

Fields are initialized by initialize_output_structures()

Calculated

ebal()

Output file

• fluxes.csv

if options.calc_vert_profiles & options.calc_ebal soil fluxes will also be recorded, because soil is the 61st layer.

• leaftemp.dat

• layer_h.dat

• layer_le.dat

• layer_a.dat

• layer_rn.dat

Variations

Various absorbed photosynthetically active radiations (aPAR) can be calculated by ebal() (if options.clc_ebal) or by SCOPE.m

Used

variable	user
aPAR_Cab_eta -> rad.Femtot	SCOPE (if options.calc_fluor)
aPAR_Wm2 -> fPAR	output_data()
