EGU General Assembly 2018. Vienna (Austria), 8-13 Abril 2018. .- https://meetingorganizer.copernicus.org/EGU2018/EGU2018-6622.pdf In the past decades, atmospheric chemists have come to realize that halogen species (like Cl, Br or I and their ox-ides ClO, BrO and IO) exert a powerful influence on the chemical composition of the troposphere and through thatinfluence affect the evolution of pollutants, hence having a significant impact on climate. These reactive halogenspecies are potent oxidizers for organic and inorganic compounds throughout the troposphere. In particular, halo-gen cycles can act on several compounds (such as methane, ozone, particles. . . ), all of which are climate forcingagents through direct and indirect radiative effects.
