Hb. Su et al., DEVELOPMENT OF A COUPLED LEAF AND CANOPY MODEL FOR THE SIMULATION OF PLANT-ATMOSPHERE INTERACTION, Journal of applied meteorology, 35(5), 1996, pp. 733-748
A numerical scheme was developed to couple a multilayer canopy radiati
on model, a photosynthesis model for C-3 species, and a leaf stomatal
conductance model with a single leaf energy balance equation. This cou
pled leaf and canopy model was used to simulate the responses of a hor
izontally uniform forest canopy to its ambient microenvironment, using
micrometeorological data collected from field measurements in a fores
t canopy. Emphasis was placed on issues associated with modeling the t
ransient responses of plant leaves. For example, thermal storage was f
ound to be important in modeling transience of leaf temperature, which
in turn influenced the transient heating or cooling of the atmosphere
by plant leaves. In addition, modification of the Ball-Berry leaf sto
matal conductance model, using an exponential formula with an empirica
l time lag, yielded more realistic transient leaf stomatal conductance
s, which were important for estimating evaporation and CO2 assimilatio
n.
