H: sensible heat flux density (W / m^2)

H: sensible heat flux density (W / m^2)

.get_H(T_leaf, pars, unitless)

Arguments

T_leaf

Leaf temperature in Kelvin

pars

Concatenated parameters (leaf_par, enviro_par, and constants)

unitless

Logical. Should function use parameters with units? The function is faster when FALSE, but input must be in correct units or else results will be incorrect without any warning.

Value

Value in W / m\(^2\) of class units

Details

$$H = P_\mathrm{a} c_p g_\mathrm{h} (T_\mathrm{leaf} - T_\mathrm{air})$$

Symbol	R	Description	Units	Default
\(c_p\)	c_p	heat capacity of air	J / (g K)	1.01
\(g_\mathrm{h}\)	g_h	boundary layer conductance to heat	m / s	calculated
\(P_\mathrm{a}\)	P_a	density of dry air	g / m^3	calculated
\(T_\mathrm{air}\)	T_air	air temperature	K	298.15
\(T_\mathrm{leaf}\)	T_leaf	leaf temperature	K	input
