Plant water stress factor was calculated using soil moisture stress (SMS) parameterization before plant hydraulics stress (PHS) scheme was implemented.
Volumetric soil water content at 50 cm depth with soil moisture stress (SMS) parameterization (middle panel column in the following table) using ELM differs from those simulated by CLM5 (Figure (a) in the third panel column in the following table) in Kennedy et al. The discrepancy in soil water simulation between ELM and CLM5 will result in model discrepancy when using plant hydraulic stress (PHS) in ELM. However, similar to CLM5 (Figure a,c in the third column), ELM-PHS simulates wetter soil in the dry season (Figure in the first column) compared to ELM-SMS (Figure in the second column).

The following two figure shows two figures in the table below show stress factor (BTRAN) comparison with (leftsecond column) and without PHS (middlefirst column) in Sep, Oct and Nov of 2003. They are higher compared to the Kennedy paper (solid line in the third panel column in the the table below). The discrepancy may be caused by the Medlyn photosynthesis model and soil water calculation in CLM5.

As the soil moisture simulations don't match between the models, the match between ELM and CLM5 in terms of plant organ water potentials is not expected. However, similar to CLM5 simulation (Figure (a) in the bottom right panel), root water potential is higher than the others and there is almost no discrepancy among stem, leaves (top figure below).
