Research from MIRAGE (Megacities Impacts on Regional and Global Environments), a field campaign held in Mexico City in 2006, is coming to fruition as scientists begin to publish their findings. A new paper details the ozone “weekend effect” in Mexico City and its implications for local air pollution.
