Short summary

Surface ozone concentrations in Mexico City frequently exceed the Mexican standard and have proven difficult to forecast due to changes in meteorological conditions at its tropical location. The Madden–Julian Oscillation (MJO) is largely responsible for intraseasonal variability in the tropics. Surface ozone in Mexico City is modulated by the MJO through its circulation pattern in the upper troposphere and its associated cloudiness, thus modulating solar radiation reaching the boundary layer.
