The Doppler Lidar (DL) is a ground-based lidar system used to measure radial velocity and attenuated aerosol backscatter. It detects aerosol backscatter in the near-infrared (1.5 microns) and uses coherent detection to measure the Doppler frequency shift of the backscatter signal to determine radial velocity. It features a range gate size of 18 to 60 meters, a typical maximum data range of 9.6 km, and a temporal resolution of 0.01 to 30 seconds. The Department of Energy operates DLs at its Atmospheric Radiation Measurement (ARM) User Facility sites.
