Short summary
This paper presents the development and evaluation of a hybrid Lagrangian-Eulerian modeling tool based on the CMAQ model. In this tool, a small sub-domain consisting of grid cells in horizontal and veridical directions follows a trajectory defined by the mean mixed-layer wind. The advantage of this tool compared to other Lagrangian models is its capability to utilize realistic boundary conditions that change with space and time as well as a detailed treatment of chemical reactions.
