Compact Micro-Pulse Backscatter Lidar and Examples of Measurements in the Planetary Boundary Layer

摘要

We present a micro-pulse depolarization-backscatter lidar for unattended measurements. The presented lidar originates from a lidar for a high-altitude aircraft, what is demonstrated in its compactness and the possibility for transportation with minimum resources. The lidar determines the aerosol backscatter coefficient in the PBL and lower troposphere, as well as the mixing layer height during the overall diurnal cycle. As examples of the lidar operation we present selected cases of the aerosol stratification above Neuchatel, Switzerland (47.002°N, 6.955°E, 487m asl).
