By Engelmann, Ronny Wandinger, Ulla; Ansmann, Albert; Muller, Detlef; Zeromskis, Egidijus; Althausen, Dietrich; Wehner, Birgit ABSTRACT The vertical aerosol transport in the planetary boundary layer (PBL) is investigated with lidars. Profiles of the vertical wind velocity are measured with a 2-[mu]m Doppler wind lidar. Aerosol parameters are derived from observations with an aerosol Raman lidar. Both instruments were operated next to each other at the Institute for Tropospheric Research...
