The purpose of this study was to evaluate the variability of the concentration of carbon monoxide (CO) and ozone (O3) over the Metropolitan Region of Manaus (RMM), analyzing its relationships with fires and El Niño Southern Oscillation (ENSO) events, from the Atmospheric Infrared Sounder (AIRS) sensor data on board the AQUA satellite for the period from 2003 to 2015. The results showed a similar behavior in relation to the seasonal cycle of the monthly average concentrations of O3 and CO, with the lowest values of CO and O3 occurring in the first half of the year and a gradual increase from June, with peaks in September and October. Due to highest occurrence of fires in the region during its dry season. In relation to the variability associated with ENSO, an increase in O3 and CO concentrations was observed in the year 2015, classified as year of El Niño, in relation to the year 2008 and 2011, classified as La Niña year. The observations made by the environmental satellite AQUA provide a set of useful data for conducting studies on the relationship between climatic conditions and atmospheric pollution levels in the region.
