Top: Height-time display of wind speed and direction.Bottom: Height-time displays of vertical velocity variance, skewness, and kurtosis. The ARM Facility currently operates several scanning coherent Doppler lidar systems at various sites around the globe. These instruments operate in the near infrared and provide measurements of radial velocity, attenuated aerosol backscatter, and signal-to-noise ratio. Previously shared…

Height-time display of wind speed (colors) and direction (arrows) from the Doppler lidar at the Southern Great Plains site for October 4, 2012. Vertically resolved wind measurements are crucial for numerical weather prediction and for modeling pollutant and aerosol transport. The scanning, coherent Doppler lidars operated by the ARM Facility have the capability of providing…
