Abstract:
A hybrid Lagrangian-Eulerian modeling tool has been developed using the CMAQ code. It is a moving nest domain that resides in a base Eulerian model with the same vertical CMAQ structure and physical and chemical interactions. It may follow the trajectory defined by the mean mixed-layer wind or any other user defined trajectory. It was developed as a computationally efficient 3-D grid sub-model for the purpose of evaluations of the source-receptor relationship. The correctness of the algorithms and the overall performance was evaluated against CMAQ simulation results.
