AB: In this paper we present the simulation of the global density of the Earth Plasmasphere created from the column density data observed simultaneously from the side and top of the plasmasphere, using X-CT technique. The column density data observed from the side of the plasmasphere is expected from the 30.4nm image data of the EUV Imager (EUVI) onboard the lander of the Second Phase of the Chinese Lunar Exploration Program (2ndCLEP) proposed to be launched around 2013. Where data observed from the top side is the images of the EUVI onboard KuaFu B1 and B2 in a High Elliptical Orbit. Observed simultaneously with 2ndCLEP. The orbit of KuaFu B1 and B2 are high elliptical orbit, similar with the orbit of IMAGE satellite, Two models of the initial distribution of the global density of the Earth Plasmasphere are supposed. The simple one is supposed that the initial distribution in L < 4 Earth radii (Re) is uniform, and is equal to 0 when L > 4Re. We try to check if there is a sharp boundary in L=4Re, by reconstructing the distribution of global density of the plasmasphere, created from the column density data of this simple model observed simultaneously from the side and top of the plasmasphere, using X-CT technique. The second model is the Horwitz's plasmasphere Model based on DE satellite observation, and used to prove if it will be reverted to the original density distribution, after data reconstruction. Our results show that a sufficient number of views must be used in order to reconstruct the density of the plasmasphere, and only data during the quite time with small variation can be reconstructed.
