The air quality of cities is the result of complex natural and anthropogenic relationships. Many districts in the city of Metropolitan Lima have concentrations of particulate material that exceed the air quality standards (ECA) for PM10 (150 μg / m3) and PM2.5 (25 μg / m3). Exposure to high concentrations of air pollutants generates negative effects on health. Vehicle emissions are a very important source of pollutants, the average values of pollutants provide a mechanism to analyze changes in long times. The variability in this thesis is related to the concentrations of PM10 and PM2.5 that tells us how far away the concentrations of the average value are and help to make important social decisions. This thesis work aims to estimate PM10 and PM2.5 particulate matter concentration for Metropolitan Lima using the Eulerian mesoscale numerical model Weather Research and Forecasting / Chemistry (WRF-chem). This online model serves both atmospheric research and weather-chemical forecasting needs, for which it makes use of simultaneous information from meteorology and chemistry. The study periods correspond to the months of February and July 2016, chosen for the high and low levels of atmospheric pollutants. The model estimated the concentrations of chemical species PM2.5 and PM10, information that was compared with data recorded at the surface level by ten SENAMHI air quality stations: Campo de Marte (CMD), Ate (ATE), San Borja (SBJ), Santa Anita (STA), Carabayllo (CRB), Huachipa (HCH), Puente Piedra (PPD), San Martin de Porres (SMP), Villa María del Triunfo (VMT) and San Juan de Lurigancho (SJL). This allowed us to know to what extent the diurnal cycles of PM10 and PM2.5 are influenced by vehicle emissions in the two selected periods. A numerical model is Eulerian when it captures concentration or meteorological information at fixed points in space. The WRF-chem model was developed by the National Center for Atmospheric Research (NCAR) in collaboration with other North American institutions, including National Oceanic and Atmospheric Administration (NOAA) and National Centers for Environmental Prediction (NCEP).
