The objective of this work was to numerically simulate the concentration of atmospheric pollutants PM10 and PM.2.5 and their relationship with meteorological conditions in Metropolitan Lima (Perú). The open source scientific program CCATT-BRAMS (INPE / CPTEC Brazil) was used. The observed data of the meteorological variables and the concentrations of PM10 and PM.2.5 were obtained from the National Service of Meteorology and Hydrology of Perú (SENAMHI). The simulated concentrations of PM10 and PM2.5 were obtained by the numerical program of chemical transport CCATT and the meteorological variables obtained by the numerical model of the atmosphere BRAMS. The results were validated with the observed data. Results show that there is influence of the increase in wind speed and relative humidity on the decreasing in PM10 in both summer and winter.
