Controlling Factors of Oxidants and Aerosols in the Upper Troposphere and Lower Stratosphere and the Anthropogenic Influence (COATS) (C07)

• Subject Area: Atmospheric Science
• Term: since 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 428312742

The budget of gas phase tracers and aerosols in the UT/LS region will be numerically investigated. The drivers for ozone and OH in this area will be explored, analyzing the roles of convective transport and lightning. Similarly, we will identify the sources and sinks of aerosols, investigating the importance of newly discovered nucleation channels and determining the radiative role of aerosols in the UT/LS. Importantly, observations will be used to validate the numerical results. Finally, we will assess the anthropogenic impact on this region through sensitivity studies.
