Short summary

Few studies have investigated the effects of initial conditions on the simulation or prediction of PM_2.5 concentrations. Here, sensitivity experiments are used to explore the effects of three initial mechanisms (clean, restart, and continuous) and emissions in Xi’an in December 2016. According to this work, if the restart mechanism cannot be used due to computing resource and storage space limitations when forecasting PM_2.5 concentrations, a spin-up time of at least 27 h is needed.
