ftran_tot_iso

Description

This is the fraction of the incident isotropic diffuse radiation - passing through a planar reference surface of specified lateral dimension and elevation above the target, and oriented perpendicular to the underlying surface normal - that passes in downward direction through a second identical (virtual) reference plane located at the level of the background surface at z = ~ 0. ftran_tot_iso includes uncollided radiation, radiation collided with the canopy only, and also contributions due to radiation that is reflected back up from background before being scattered down to the background again by the canopy. ftran_tot_iso does not include contributions from direct illumination sources (should they be prescribed in the illumination conditions of a given RAMI experiment).

ftran_tot_iso = ftran_uc_iso + ftran_coco_iso + contribution from radiation bouncing back and forth between canopy and background.
