Other AbstractBased on an analytical ion model for the ring current,in conjunction with the Chamberlain exosphere density model,Energetic Neutral Atom(ENA) images were calculated for the magnetic storm occurred in November 2004.It was shown that the simulated ENA images differ from images recorded by the Energetic Neutral Atom Detector Unit(NUADU) instrument aboard TC-2 of Double Star mission in terms of azimuth/magnetic Local Time(MLT) distribution,altitude /latitude distribution and energy spectral distribution.If the determiner of asymmetry of the ring current and azimuth of flux maximum can be selected according to evolvement of storms,and more emphasis be placed on density of low altitude exosphere or neutral atoms other than H be taken into account,the ion model is hopeful to produce more precise ring current ion distributions and ENA images.In addition,the ion spectrum at the injection region is expected to be revised and change of ratio of different ion species should be taken into account in order to get better simulation results.
