The article presents analysis of optical and microphysical aerosol properties, and their distribution in atmosphere over Kyiv city using lidar and sun-photometer observation at the beginning of September 2015. This period of time characterized with forest and peat fires nearby and at suburb of Kyiv. Observations were carried out with the CIMEL370 lidar and the sun-photometer of the AERONET Kyiv station located on the roof of the Main astronomical observatory of the NAS of Ukraine. The recently developed GARRLiC (Generalized Aerosol Retrieval from Radiometer and LIDAR Combined Data) algorithm was used for data analysis. It was established that at the beginning of the event (1-2 September) typical atmosphere with insignificant aerosol content was observed. A large amount of combustion products which increase aerosol content in several times has arrived into Kyiv from north-north-west direction starting from evening of 2 September. Range resolved aerosol properties were obtained in the first time for Ukraine region. Comparison with the corresponding values of aerosol properties obtained by the AERONET algorithm is made.
