Core Function Called to Solve Equation for Soil Temperature

The function called by soil_temperature_function to solve equation for soil temperature from Beckman et al. (1973) .

soil_temperature_equation(L, rho_a, c_a, u_inst, z_r, z0, T_inst, T_s)

Arguments

L

numeric Monin-Obukhov length, a measure of the instability of heat flow (see Beckman et al. (1973) ).

rho_a

numeric density of air (kg m^-3).

c_a

numeric specific heat of air (J kg^-1 C^-1).

u_inst

numeric instantaneous wind speed (m s^-1).

z_r

numeric reference height (m).

z0

numeric surface roughness (m).

T_inst

numeric instantaneous air temperature (C).

T_s

numeric initial soil surface temperature (C).

Value

numeric soil temperature (C).
