This study evaluates the temporal analysis of the concentration of NOX and O3 registered in Lima Metropolitana in the period 2015 – 2018, its correlation and the influence of air temperature and solar radiation on these gases. As part of the methodology, the hourly data for NO2, NO, O3, air temperature and solar radiation recorded by SENAMHI and PROTRANSPORTE stations were processed, the hourly NOX concentrations was estimated from the sum of the hourly concentrations of NO and NO2; statistical descriptors were calculated; graphs were generated at different time scales; and correlational analyzes based on the Spearman coefficient and multiple linear regression analyzes were performed for the NOX and O3 levels. The results showed that neither the hourly nor annual levels of NO2 and O3 exceeded the Peruvian ENCA or did not comply with the WHO guidelines for the period between 2015 – 2018. In addition, significant positive correlations were obtained between NOX and negative correlations between O3 and NOX and multiple linear regression equations with high coefficients of determination takin into account meteorological parameters. Finally, it was concluded that the hourly behavior of these gases was mainly influenced by vehicular traffic and solar radiation; the daily variation, due to the “weekend effect”; the monthly and seasonal behavior, due to the intensity of thermal inversion layer and solar radiation; and the multi-year behavior showed a slight upward trend for NOX levels. Furthermore, the hourly behavior of O3 was more related to meteorological parameters; while that of the NOX, with vehicular traffic.
