This paper presents the results of a numerical study of urban pollution climatologies using green barriers. Nowadays urban climatology is becoming a hot topic. Air quality has a significant impact on human health. For the numerical solution of this problem, the test problem was solved. To assess the applicability of the mathematical model, the numerical algorithm and the choice of the optimal turbulent model, experimental data and numerical calculations by other authors were used. The obtained numerical simulation results are in good agreement with the experimental results and the numerical results of other authors. And to obtain more accurate numerical results for the experimental data, there was a certain corresponding turbulent model. Further, for all numerical solutions, a certain optimal turbulent DES model was used. And also the influence of green continuous and discontinuous barriers on the concentration distribution was considered. To reveal the optimum barrier height, experimental data were used. As a result of the concentration spread between the continuous and the discontinuous barrier, there is a significant difference in the dependence on the height of the barrier and the concentration of pollutants at ground level decreases as compared to the green discontinuous barrier. The results can help city planners in green infrastructure and protect urban climatologies from pollution.
