Abstract | Sonic anemometry represents an important technological advance for aeolian studies, fostering better understanding of near-surface turbulence and improved methods for estimating shear velocity (u*). Here, we compare u* estimated from the Law of the Wall approach and from four methods that use 3-D wind vector measurements from sonic anemometers: double rotation, triple rotation, planar fit, and a newly developed approach based on invariants of the Reynolds stress tensor. Data were collected over 7.5 months at the Jornada Experimental Range |
