Short summary
A new treatment was implemented into a microphysics scheme in WRF-Chem to quantify and evaluate the effect of dust on the ice nucleation process. The simulation of atmospheric IWC during a typical dust-intensive period over East Asia was substantially improved with the effect of dust considered in the model. In addition, sensitivity experiments were carried out to optimize the parameters used in the implemented treatment.
