Our findings support the use of VOD for plant hydraulic studies in temperate forests.  ...  We measured stem xylem and leaf water potentials of trees within the stand and retrieved VOD with a single-channel algorithm based on continuous radiometer measurements and measured soil moisture.  ...  We are grateful to Mark VanScoy and Audrey Plotkin-Barker for logistical support at Harvard Forest. Financial support.  ...
