According to the inventories carried out by the air pollution control agencies, vehicle emissions are responsible for more than 70% of air pollutants in metropolitan regions. Proper handling of CMAQ input data is an important step in the formation of a database for the model. Thus, it is necessary to insert the meteorological data using the Weather Research and Forecasting (WRF) version 3.9 in the period of the 31 days of January 2013. Four domains with resolutions of 27, 9, 3 and 1 kilometers were used and 21 vertical layers. Spatial Allocator (SA) was used to format the maps and extract the data necessary for the construction of the SMOKE emissions inventory files. WRF was validated comparing the simulation results with data from two weather stations (Jardim Primavera and Nova Iguaçu), using the statistical methods MB, MAGE, RMSE and IOA. SMOKE presented a constant time profile, this occurred because the established hourly function only contemplated daily results without taking into account the variations over the week.
