Aim: Establishment of anthropogenic aerosols change dynamics in the atmosphere of Tbilisi city, their distribution, concentration, under complex orographic and climate conditions.Methodology: For the assessment of climate change for Tbilisi city, air pollution monitoring materials were used from the National Environmental Agency where observation was carried out for the background air pollution and also concentrations of aerosols and harmful substances were measured in automatic mode. The results of four stages of indicatorwere presented. Statistical, climatic and graphical analysis were used for research.Results: The basic pollutants: (carbon dioxide, sulfur dioxide, nitrogen oxides, ozone, PM2.5 and PM10 (monthly and annual concentrations) in most cases, exceeded MPC. Nitrogen oxides and ground ozone were particularly sensitive, average annual concentrations was 1.4-1.8 times and exceeded the MPC, which affected the health of the population. It is noteworthy, that for last 5 years in Tbilisi, average annual concentration of lead decreased. Climate change expression often have a complex character, which especially complicates the determination of causal relationship between them and requires right approach and proper definition of adaptation measure.Interpretation: Meteorological elements play an important role in aerosol's accumulation in the atmosphere. There was a correlation between meteorological elements and atmosphere polluting ingredients. Pollutants concentration on the surface layer frequently exceeded MPC, i.e., promoted by physical-geographic state and meteo-climate conditions due to which urban microclimate change is possible.
