Equation (1) gives the main energy items of canopy
as shown in Fig. 1. Specifically, the first three items are
sensible heat exchange SH, latent heat exchange from
TR, and energy storage change of canopy, respectively.
The fourth item is net radiation, which is composed of
net shortwave and net longwave radiations [Eq. (1a)].
The calculations for the first three items are presented
in Wang et al. (2002a). The calculations for the fourth
item are presented in Wang (2005) and Wang et al.
(2007).
