Abstract：

Three-dimensional chemical transport models (CTMs) and coupled chemistry-climate models (CCMs) have been widely used to study the dynamical and chemical processes which control the distributions of atmospheric compositions.In this talk, I will mainly focus on the stratospheric ozone depletion and mesospheric metal layers. I will also brief introduce two different models and their applications for the research purposes: one is our NCAS (National Centre for Atmospheric Science) community CTM (TOMCAT/SLIMCAT,www.see.leeds.ac.uk/slimcat) whichcontains a detailed description of stratospheric and tropospheric chemistry as well as a detailed aerosol module.The model has been widely used to study transport and chemistry in the upper troposphere and lower stratosphere (UTLS) and also forWMO ozone assessment. The other is our modelling developmentbased on the NCAR Community Earth System Model (CESM): global atmospheric model of meteoric metals and meteoric smoke particles (MSPs).
