AB: The global dynamics of the ionized and neutral components in the environment of Io plays an important role in the interaction of Jupiter's corotating magnetospheric plasma with Io [Combi et al., 2002; 1998; Kabin et al., 2001]. The stationary simulation of this problem was done in the MHD [Combi et al., 1998; Linker et al, 1998; Kabin et al., 2001] and the electrodynamic [Saur et al., 1999; 2003] approaches. In this report, we study the comparative role of ionization processes and charge exchange in formation of the plasma environment near Io by means of kinetic simulation. The atmosphere of Io is considered as an immobile obstacle in simulation. The comparison of results of such simulations with the Galileo spacecraft data is also discussed in this report. ~\\ M R Combi et al., {\em J.\ Geophys.\ Res.,} {\bf 103}, 9071, 1998.\\ M R Combi, T I Gombosi, K Kabin, {\em Atmospheres in the Solar System: Comparative\ Aeronomy.
