Instrument

DAWN
Doppler Aerosol WiNd Lidar

The Doppler Aerosol WiNd Lidar (DAWN) is an active remote, airborne lidar developed by NASA Langley Research Center. DAWN uses a pulsed, solid-state laser that operates at a wavelength of 2 micrometers to detect aerosol backscatter in the atmosphere. DAWN can also provide vertical profiles of the horizontal winds below the aircraft and the line of sight winds at each azimuth angle. Typically, DAWN provides profiles at a resolution of 60 m and emits a pulse at a rate of 10 Hz.
