Dual-Doppler Lidar Measurements During Multi-Month Field Campaign

A coordinated wind lidar system was utilized during a multi-month campaign to characterize wind conditions in the Planetary Boundary Layer. Understanding wind conditions in this dynamic layer of the atmosphere is critical to ensure safe and reliable aircraft operations to include Uncrewed Aircraft Systems (UAS). The dual-Doppler lidar technique was first demonstrated by NASA for Advanced Air Mobility (AAM) applications. Using this technique, continuous resolved wind vectors at low altitudes were successfully measured. Unexpectedly, a hurricane formed off the coast of California and its remnants made landfall and passed through the test site. The coordinated dual-Doppler lidars ran continuously through an extreme weather event and successfully measured wind dynamics caused by the storm. This work will focus on the deployment of a multi-lidar setup and analyzing the wind dynamics caused by the storm.
