Title: Vertical wind and backscatter profiles, along with cloud base height, from Doppler lidar Location: Belle Mina Site for Vortex-SE-2016 Lat/Lon: 34.690 degN, -86.885 degE Date updated: 15 August 2016 Contact: Dave Turner and Temple Lee, NOAA (dave.turner@noaa.gov, temple.lee@noaa.gov) System: Leosphere 100-S lidar, which was deployed by NOAA Air Resources Lab beside the CLAMPS-1 facility --- Background Doppler lidars transmit pulses of 1.5 um wavelength laser energy into the atmosphere, which scatters off aerosol particles and hydrometeors. The lidar measures the intensity of this return, as well as its radial velocity. The lidar has a scanner which allows the system to scan anywhere in the hemisphere, and typically a fixed scan strategy is used. These data are when the scanner was pointing vertically, and thus this is a measure of the vertical motions of the atmosphere. Due to the high temporal resolution of the data, turbulence profiles (e.g., 2nd and 3rd moment profiles) of the vertical motion can be derived (e.g., see Bonin et al. 2015). Temporal gaps in the dataset of approximately 1 minute each are due to periods when the lidar was making other scans (e.g., PPIs from which the horizontal wind speed and direction are derived). This dataset was collected north of Belle Mina, Alabama, during the VORTEX-SE-2016 field campaign. This lidar is the Leosphere 100-S system. This lidar was deployed directly beside the Collaborative Lower Atmospheric Mobile Profiling System (CLAMPS-1). It started operations on 11 March and continued until May 2. --- References Bonin, T.A., W.G. Blumberg, P.M. Klein, and P.B.
