Abstract: We compared the observed total dust deposition fluxes during precipitation (TDP) mainly at Toyama in Japan during the period January – April 2009 with results available from four NASA GEOS-5 global model experiments. The modeled results were obtained from three previous experiments and carried out in one experiment, which were all driven by assimilated meteorology and simulating aerosol distributions for the time period. We focus mainly on the observations of two distinct TDP events, which we…
