This study includes the temporal analysis of the levels of NO2, CO, and ground-level O3 measured in Lima Metropolitana between the years 2015 to 2018 and the relationship between them and with air temperature and solar radiation. For this, descriptive, correlational, and regression temporal analyzes were carried out using hourly records taken in different areas of the city. The levels of the gases evaluated were mainly below the Peruvian regulations and the World Health Organization's air quality guidelines, so their influence on the health of the population was not relevant. The hourly levels of these gases were bimodal and were influenced by vehicular traffic for NO2 and CO, and by solar radiation for ground-level O3; although, the latter may also have been influenced by its nocturnal movement. Daily behavior showed the so-called "weekend effect". The correlation analysis indicated a h...
