radiatively and S/T exchanges) still imperfectly described in existing models. This will be valuable to improve knowledge about the processes occurring in the upper troposphere/ lower stratosphere (UT/LS), and the model treatment of near tropopause chemistry and transport.
Current models fail to fully capture radiatively and S/T exchanges. This knowledge gap will be crucial in improving comprehension of the UT/LS environment, particularly regarding near-tropopause chemistry and transport processes.
