Vertical aerosol distribution in the southern hemispheric midlatitudes as observed with lidar in Punta Arenas, Chile (53.2° S and 70.9° W), during ALPACA
Within this publication, lidar observations of the vertical aerosol distribution above Punta Arenas, Chile (53.2 ∘ S and 70.9 ∘ W), which have been performed with the Raman lidar Polly XT from December 2009 to April 2010, are presented. Pristine marine aerosol conditions related to the prevailing we...

Within this publication, lidar observations of the vertical aerosol distribution above Punta Arenas, Chile (53.2 ∘ S and 70.9 ∘ W), which have been performed with the Raman lidar Polly XT from December 2009 to April 2010, are presented. Pristine marine aerosol conditions related to the prevailing westerly circulation dominated the measurements. Lofted aerosol layers could only be observed eight times during the whole measurement period. Two case studies are presented showing long-range transport of smoke from biomass burning in Australia and regionally transported dust from the Patagonian Desert, respectively. The aerosol sources are identified by trajectory analyses with the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) and FLEXible PARTicle dispersion model (FLEXPART). However, seven of the eight analysed cases with lofted layers show an aerosol optical thickness of less than 0.05. From the lidar observations, a mean planetary boundary layer (PBL) top height of 1150 ± 350 m was determined.
