Lower Troposphere Observation over Urban Area with Lidar at 1064 nm

الملخص EN

An episode of relatively thick (till ~3 km) aerosol formation over the urban area of Sofia city was observed by lidar at a wavelength of 1064 nm.

The lidar is part of Sofia lidar station at the Institute of Electronics of Bulgarian Academy of Sciences.

Analysis of the weather conditions during the measurement period explains the stable persistence of such formation of human-activity aerosol over the town for the days of observation 20, 21, 23, and 24 June, 2011.

The estimated top of the Planetary Boundary Layer for the measurement dated 23 June showed unusually high altitude ~2200 m above ground.

The results are presented in terms of vertical atmospheric backscatter coefficient profiles and color maps of the aerosol stratification evolution.
