The Extreme Ultra-Violet Camera (hereafter EUVC) is a scientific payload onboard the lander of the Chang’E-3 (hereafter CE-3) mission launched on December 1st, 2013. Centering on a spectral band around 30.4 nm, EUVC provides the global images of the Earth’s plasmasphere from the meridian view, with a spatial resolution of \(0.1~R_{\oplus}\) in \(150 \times 150~\mbox{pixels}\) and a cadence of 10 minutes. Along with the data being publicly released online, some unsettled issues in the early stage have been clarified, including the geometrical preparations, the refined approach on the coefficient \(K\) for the background, and the alignment among the images. A demo of data after all the above processes is therefore presented as a guidance for users who are studying the structure and dynamics of the plasmasphere.
