Understanding wind conditions is critical for the NASA Advanced Air Mobility (AAM) mission. The types of aircraft, and the region of the atmosphere they operate in, make them highly susceptible to wind effects. We demonstrate the feasibility of using wind lidar to measure wind dynamics for the AAM mission. Wind vector measurements from two Doppler wind lidars using dual-Doppler techniques are compared with in situ measurements from a ground-based sonic anemometer and small uninhabited aircraft systems (sUAS). Both lidar beams intersected directly above a sonic anemometer and measurements were compared. The resulting root mean square error values between the two instruments’ speed and direction measurements were 1.72 m/s and 23.05 deg, respectively. Following this test, a dual-Doppler scan pattern which measured wind vectors along a vertical column was performed while a sUAS measured wind vectors along the scanned volume for comparison. The wind profiles from the two measurement techniques are consistent and demonstrate the potential of using Doppler lidar for AAM.
