Untch AU - the team AB - With the formal end, within the GEMS project, of the period of development of the forward forecast model including aerosol processes, this report presents the state of the aerosol modelling in the ECMWF Integrated Forecasting System (IFS). It details the various parametrisations used in the IFS to account for the presence of tropospheric aerosols. Details are given of the various formulations and data-sets for their sources and of the parametrisations describing the sinks. Comparisons of monthly mean and daily aerosol quantities like optical depths against satellite and surface observations are presented. The capability of the forecast model to simulate aerosol events is illustrated through comparisons of dust plume events.
