The role of temperature in tropospheric ozone

After evaluating some meteorological simulations, we detect an error of over 5°C in surface temperature. In order to assess the effect of this anomaly in temperature, we perform new simulations of an emission model and a photochemical model using the correct surface temperature in the meteorological data. Our goal is not to solve the problem in surface temperature estimates, but to reveal how it affects the air quality model. Our results show an increase in some maximum daily ozone levels, but they do not reveal any important change in the global pattern of ozone concentrations.
