Actual evaporation

Actual evaporation from the canopy is limited either by the potential interception evaporation rate, E^*_ip, or by the interception storage, S_i:

                                   (3.67)

where S_i(t-1) is the residual intercepted water which remains from the previous time step (∆t) if the actual evaporation, E_ia, was smaller than the interception storage. Remaining intercepted water at the present time step, S_i(t), is calculated as:
