Early in 1967 a series of observations using pulsed ruby and neodymium lidars were made near Independence, California the object of these observations was to establish the value of lidar for studying air motion in the Sierra wave, with special reference to indications of turbulence. Although no major wave activity occurred, wave motions were observed, both in what appeared to the eye to be clear air and in air where the particulate matter was sufficiently concentrated as to be visible as clouds. Interruptions in the smooth laminar flow in the clear air were observed, and measurements were made of the length, amplitude, and height of waves shown by clouds. It is concluded that lidar observations are of great value in studying wave motion, even in the absence of visible cloud. Modified author abstract
