• Focus on ozone (3º most important GHG)
• Ozone is formed from CO, CH4, NOx, VOC and sunlight
• Indirect effect of CO on OH-CH4-O3 equilibrium
• Except H2O and CO2, all other species are removed by
chemical reactions
• Main route is the reaction with OH e HO2 at troposphere
• N2O, PFC, SF6, CFC and halons are removed at stratosphere
