Based on the characteristics of the solar wind ion flux data fetched by Chang’E-1 (CE-1) moon-orbiting spacecraft

a new visualization analysis method for these data is developed. First

all the data fetched in a month is separated depending on whether they are obtained on the day-side or the night-side of the moon. Then the total flux intensity distributed in certain energy levels is calculated as the sole flux intensity value for each data record

and these flux intensity values are projected to an even longitude-latitude grid of the moon surface and an average intensity value is calculated for each grid which has multiple intensity values projected in. Finally after a map projection

e.g. Hammer projection to give a more conventional representation of the moon surface and a color theme is chosen to represent different intensities of ion flux

and so an intuitive visualization result of the distribution of ion flux on the day-side or the night-side of the moon in a month is obtained. By using this method it is possible to visualize and analyze the mass data of the distribution and fluctuation of solar wind ion flux in cislunar environment. The validity of this method is proven by the results of actual experiments.
