Abstract

In this work the results of an experimental assessment of the operation accuracy of three lidar systems in Sofia City are presented. The investigation was carried out performing an inter-comparison of profiles of the atmospheric aerosol backscattering coefficient simultaneously measured by the lidars. All three lidar systems are involved in regular measurements within the frame of the EARLINET-ASOS (European Aerosol Research Lidar Network: Advanced Sustainable Observation System) European project. Twenty-four lidar stations, distributed over 16 countries in Europe are associated in this network. The main objective of the project is the establishment of a large statistical database of the aerosol distribution on the European scale. In order for the data to be reliable, preliminary tests of the quality of work of the individual lidar systems should be performed. That was the reason to perform the present study. The experiments on simultaneous operation of the lidar systems were carried out according to the fixed EARLINET-ASOS schedule starting in April 2006. The mean difference in the aerosol backscatter for all profiles obtained simultaneously and the standard deviation of the differences were calculated and compared.
