AB: NOAA's Earth System Research Laboratory (ESRL) has developed and deploys two coherent Doppler lidars to study boundary layer dynamics. These systems, which operate at 2 and 9 microns, use high pulse rates and motion-compensated hemispheric scanning to provide profiles of horizontal wind speed and direction, backscatter intensity, vertical velocity, and velocity variances from a variety of stationary and moving platforms: land based as well as ship and aircraft based. Operating the systems with low elevation angle vertical and horizontal sector scans permits study of evolving low-level horizontal wind fields, such as nocturnal low-level jets, flow in complex terrain, and coherent wind features generated from air/sea interactions with extremely high temporal and vertical spatial resolution. The ability to operate from moving platforms has provided a unique opportunity to study boundary layer dynamics over the ocean and over much larger horizontal scales accessible from aircraft.
