supy.util.cal_gs_mod

supy.util.cal_gs_mod(kd, ta_c, rh, pa, smd, lai, g_cst, g_max, lai_max, wp_smd, debug=False)[source]

Model surface conductance/resistance using phenology and atmospheric forcing conditions.

Parameters:
  • kd (numeric) – Incoming solar radiation [W m-2]
  • ta_c (numeric) – Air temperature [degC]
  • rh (numeric) – Relative humidity [%]
  • pa (numeric) – Air pressure [Pa]
  • smd (numeric) – Soil moisture deficit [mm]
  • lai (numeric) – Leaf area index [m2 m-2]
  • g_cst (size-6 array) – Parameters to determine surface conductance/resistance: g_lai (LAI related), g2 (solar radiation related), g_q1 (humidity related), g_q2 (humidity related), g_ta (air temperature related), g_smd (soil moisture related)
  • g_max (numeric) – Maximum surface conductance [mm s-1]
  • lai_max (numeric) – Maximum LAI [m2 m-2]
  • wp_smd (numeric) – Wilting point indicated as soil moisture deficit [mm]
Returns:

Modelled surface conductance [mm s-1]
Return type:

numeric
