Evolution of Tropospheric Ozone and Surface Temperature in Mexico City from 2000 to 2021

Year: 2025

Type: article

Abstract: We analyze the relation between maximum tropospheric ozone concentration and surface temperature in Mexico City between 2000 and 2021. Changes in ozone levels over the decades appear to respond to public strategies aimed at reducing its precursors. The exponential fit between temperature and maximum ozone concentration is [O3] = 9.33 × exp (0.0957 × T), with a coefficient of determination of 0.73, for the period 2000–2021. Reordering the data by five-year period improves the fit slightly; the intercepts increase from 8.431 (2000–2004) to 10.428 (2015–2019), and the slopes decrease from 0.1051 (2000–2004) to 0.0839 (2015–2019), providing a quantitative insight into how public strategies and policies modify air pollution and make Mexico City’s atmosphere less reactive.
